[][src]Struct bytes::BytesMut

pub struct BytesMut { /* fields omitted */ }

A unique reference to a contiguous slice of memory.

BytesMut represents a unique view into a potentially shared memory region. Given the uniqueness guarantee, owners of BytesMut handles are able to mutate the memory. It is similar to a Vec<u8> but with less copies and allocations.

For more detail, see Bytes.

Growth

One key difference from Vec<u8> is that most operations do not implicitly grow the buffer. This means that calling my_bytes.put("hello world"); could panic if my_bytes does not have enough capacity. Before writing to the buffer, ensure that there is enough remaining capacity by calling my_bytes.remaining_mut(). In general, avoiding calls to reserve is preferable.

The only exception is extend which implicitly reserves required capacity.

Examples

use bytes::{BytesMut, BufMut};

let mut buf = BytesMut::with_capacity(64);

buf.put(b'h');
buf.put(b'e');
buf.put("llo");

assert_eq!(&buf[..], b"hello");

// Freeze the buffer so that it can be shared
let a = buf.freeze();

// This does not allocate, instead `b` points to the same memory.
let b = a.clone();

assert_eq!(&a[..], b"hello");
assert_eq!(&b[..], b"hello");

Methods

impl BytesMut[src]

pub fn with_capacity(capacity: usize) -> BytesMut[src]

Creates a new BytesMut with the specified capacity.

The returned BytesMut will be able to hold at least capacity bytes without reallocating. If capacity is under 4 * size_of::<usize>() - 1, then BytesMut will not allocate.

It is important to note that this function does not specify the length of the returned BytesMut, but only the capacity.

Examples

use bytes::{BytesMut, BufMut};

let mut bytes = BytesMut::with_capacity(64);

// `bytes` contains no data, even though there is capacity
assert_eq!(bytes.len(), 0);

bytes.put(&b"hello world"[..]);

assert_eq!(&bytes[..], b"hello world");

pub fn new() -> BytesMut[src]

Creates a new BytesMut with default capacity.

Resulting object has length 0 and unspecified capacity. This function does not allocate.

Examples

use bytes::{BytesMut, BufMut};

let mut bytes = BytesMut::new();

assert_eq!(0, bytes.len());

bytes.reserve(2);
bytes.put_slice(b"xy");

assert_eq!(&b"xy"[..], &bytes[..]);

pub fn len(&self) -> usize[src]

Returns the number of bytes contained in this BytesMut.

Examples

use bytes::BytesMut;

let b = BytesMut::from(&b"hello"[..]);
assert_eq!(b.len(), 5);

pub fn is_empty(&self) -> bool[src]

Returns true if the BytesMut has a length of 0.

Examples

use bytes::BytesMut;

let b = BytesMut::with_capacity(64);
assert!(b.is_empty());

pub fn capacity(&self) -> usize[src]

Returns the number of bytes the BytesMut can hold without reallocating.

Examples

use bytes::BytesMut;

let b = BytesMut::with_capacity(64);
assert_eq!(b.capacity(), 64);

pub fn freeze(self) -> Bytes[src]

Converts self into an immutable Bytes.

The conversion is zero cost and is used to indicate that the slice referenced by the handle will no longer be mutated. Once the conversion is done, the handle can be cloned and shared across threads.

Examples

use bytes::{BytesMut, BufMut};
use std::thread;

let mut b = BytesMut::with_capacity(64);
b.put("hello world");
let b1 = b.freeze();
let b2 = b1.clone();

let th = thread::spawn(move || {
    assert_eq!(&b1[..], b"hello world");
});

assert_eq!(&b2[..], b"hello world");
th.join().unwrap();

pub fn split_off(&mut self, at: usize) -> BytesMut[src]

Splits the bytes into two at the given index.

Afterwards self contains elements [0, at), and the returned BytesMut contains elements [at, capacity).

This is an O(1) operation that just increases the reference count and sets a few indices.

Examples

use bytes::BytesMut;

let mut a = BytesMut::from(&b"hello world"[..]);
let mut b = a.split_off(5);

a[0] = b'j';
b[0] = b'!';

assert_eq!(&a[..], b"jello");
assert_eq!(&b[..], b"!world");

Panics

Panics if at > capacity.

pub fn take(&mut self) -> BytesMut[src]

Removes the bytes from the current view, returning them in a new BytesMut handle.

Afterwards, self will be empty, but will retain any additional capacity that it had before the operation. This is identical to self.split_to(self.len()).

This is an O(1) operation that just increases the reference count and sets a few indices.

Examples

use bytes::{BytesMut, BufMut};

let mut buf = BytesMut::with_capacity(1024);
buf.put(&b"hello world"[..]);

let other = buf.take();

assert!(buf.is_empty());
assert_eq!(1013, buf.capacity());

assert_eq!(other, b"hello world"[..]);

pub fn split_to(&mut self, at: usize) -> BytesMut[src]

Splits the buffer into two at the given index.

Afterwards self contains elements [at, len), and the returned BytesMut contains elements [0, at).

This is an O(1) operation that just increases the reference count and sets a few indices.

Examples

use bytes::BytesMut;

let mut a = BytesMut::from(&b"hello world"[..]);
let mut b = a.split_to(5);

a[0] = b'!';
b[0] = b'j';

assert_eq!(&a[..], b"!world");
assert_eq!(&b[..], b"jello");

Panics

Panics if at > len.

pub fn truncate(&mut self, len: usize)[src]

Shortens the buffer, keeping the first len bytes and dropping the rest.

If len is greater than the buffer's current length, this has no effect.

The split_off method can emulate truncate, but this causes the excess bytes to be returned instead of dropped.

Examples

use bytes::BytesMut;

let mut buf = BytesMut::from(&b"hello world"[..]);
buf.truncate(5);
assert_eq!(buf, b"hello"[..]);

pub fn advance(&mut self, cnt: usize)[src]

Shortens the buffer, dropping the first cnt bytes and keeping the rest.

This is the same function as Buf::advance, and in the next breaking release of bytes, this implementation will be removed in favor of having BytesMut implement Buf.

Panics

This function panics if cnt is greater than self.len()

pub fn clear(&mut self)[src]

Clears the buffer, removing all data.

Examples

use bytes::BytesMut;

let mut buf = BytesMut::from(&b"hello world"[..]);
buf.clear();
assert!(buf.is_empty());

pub fn resize(&mut self, new_len: usize, value: u8)[src]

Resizes the buffer so that len is equal to new_len.

If new_len is greater than len, the buffer is extended by the difference with each additional byte set to value. If new_len is less than len, the buffer is simply truncated.

Examples

use bytes::BytesMut;

let mut buf = BytesMut::new();

buf.resize(3, 0x1);
assert_eq!(&buf[..], &[0x1, 0x1, 0x1]);

buf.resize(2, 0x2);
assert_eq!(&buf[..], &[0x1, 0x1]);

buf.resize(4, 0x3);
assert_eq!(&buf[..], &[0x1, 0x1, 0x3, 0x3]);

pub unsafe fn set_len(&mut self, len: usize)[src]

Sets the length of the buffer.

This will explicitly set the size of the buffer without actually modifying the data, so it is up to the caller to ensure that the data has been initialized.

Examples

use bytes::BytesMut;

let mut b = BytesMut::from(&b"hello world"[..]);

unsafe {
    b.set_len(5);
}

assert_eq!(&b[..], b"hello");

unsafe {
    b.set_len(11);
}

assert_eq!(&b[..], b"hello world");

Panics

This method will panic if len is out of bounds for the underlying slice or if it comes after the end of the configured window.

pub fn reserve(&mut self, additional: usize)[src]

Reserves capacity for at least additional more bytes to be inserted into the given BytesMut.

More than additional bytes may be reserved in order to avoid frequent reallocations. A call to reserve may result in an allocation.

Before allocating new buffer space, the function will attempt to reclaim space in the existing buffer. If the current handle references a small view in the original buffer and all other handles have been dropped, and the requested capacity is less than or equal to the existing buffer's capacity, then the current view will be copied to the front of the buffer and the handle will take ownership of the full buffer.

Examples

In the following example, a new buffer is allocated.

use bytes::BytesMut;

let mut buf = BytesMut::from(&b"hello"[..]);
buf.reserve(64);
assert!(buf.capacity() >= 69);

In the following example, the existing buffer is reclaimed.

use bytes::{BytesMut, BufMut};

let mut buf = BytesMut::with_capacity(128);
buf.put(&[0; 64][..]);

let ptr = buf.as_ptr();
let other = buf.take();

assert!(buf.is_empty());
assert_eq!(buf.capacity(), 64);

drop(other);
buf.reserve(128);

assert_eq!(buf.capacity(), 128);
assert_eq!(buf.as_ptr(), ptr);

Panics

Panics if the new capacity overflows usize.

pub fn extend_from_slice(&mut self, extend: &[u8])[src]

Appends given bytes to this object.

If this BytesMut object has not enough capacity, it is resized first. So unlike put_slice operation, extend_from_slice does not panic.

Examples

use bytes::BytesMut;

let mut buf = BytesMut::with_capacity(0);
buf.extend_from_slice(b"aaabbb");
buf.extend_from_slice(b"cccddd");

assert_eq!(b"aaabbbcccddd", &buf[..]);

pub fn unsplit(&mut self, other: BytesMut)[src]

Combine splitted BytesMut objects back as contiguous.

If BytesMut objects were not contiguous originally, they will be extended.

Examples

use bytes::BytesMut;

let mut buf = BytesMut::with_capacity(64);
buf.extend_from_slice(b"aaabbbcccddd");

let splitted = buf.split_off(6);
assert_eq!(b"aaabbb", &buf[..]);
assert_eq!(b"cccddd", &splitted[..]);

buf.unsplit(splitted);
assert_eq!(b"aaabbbcccddd", &buf[..]);
