[]Struct nix::fcntl::OFlag

pub struct OFlag { /* fields omitted */ }

Configuration options for opened files.

Methods

impl OFlag

pub const O_ACCMODE: OFlag

Mask for the access mode of the file.

pub const O_APPEND: OFlag

Open the file in append-only mode.

pub const O_ASYNC: OFlag

Generate a signal when input or output becomes possible.

pub const O_CLOEXEC: OFlag

Closes the file descriptor once an execve call is made.

Also sets the file offset to the beginning of the file.

pub const O_CREAT: OFlag

Create the file if it does not exist.

pub const O_DIRECT: OFlag

Try to minimize cache effects of the I/O for this file.

pub const O_DIRECTORY: OFlag

If the specified path isn't a directory, fail.

pub const O_DSYNC: OFlag

Implicitly follow each write() with an fdatasync().

pub const O_EXCL: OFlag

Error out if a file was not created.

pub const O_FSYNC: OFlag

Same as O_SYNC.

pub const O_LARGEFILE: OFlag

Allow files whose sizes can't be represented in an off_t to be opened.

pub const O_NOATIME: OFlag

Do not update the file last access time during read(2)s.

pub const O_NOCTTY: OFlag

Don't attach the device as the process' controlling terminal.

pub const O_NDELAY: OFlag

Same as O_NONBLOCK.

pub const O_NOFOLLOW: OFlag

open() will fail if the given path is a symbolic link.

pub const O_NONBLOCK: OFlag

When possible, open the file in nonblocking mode.

pub const O_PATH: OFlag

Obtain a file descriptor for low-level access.

The file itself is not opened and other file operations will fail.

pub const O_RDONLY: OFlag

Only allow reading.

This should not be combined with O_WRONLY or O_RDWR.

pub const O_RDWR: OFlag

Allow both reading and writing.

This should not be combined with O_WRONLY or O_RDONLY.

pub const O_RSYNC: OFlag

Similar to O_DSYNC but applies to reads instead.

pub const O_SYNC: OFlag

Implicitly follow each write() with an fsync().

pub const O_TMPFILE: OFlag

Create an unnamed temporary file.

pub const O_TRUNC: OFlag

Truncate an existing regular file to 0 length if it allows writing.

pub const O_WRONLY: OFlag

Only allow writing.

This should not be combined with O_RDONLY or O_RDWR.

pub const fn empty() -> OFlag

Returns an empty set of flags

pub const fn all() -> OFlag

Returns the set containing all flags.

pub const fn bits(&self) -> c_int

Returns the raw value of the flags currently stored.

pub fn from_bits(bits: c_int) -> Option<OFlag>

Convert from underlying bit representation, unless that representation contains bits that do not correspond to a flag.

pub const fn from_bits_truncate(bits: c_int) -> OFlag

Convert from underlying bit representation, dropping any bits that do not correspond to flags.

pub const fn is_empty(&self) -> bool

Returns true if no flags are currently stored.

pub const fn is_all(&self) -> bool

Returns true if all flags are currently set.

pub const fn intersects(&self, other: OFlag) -> bool

Returns true if there are flags common to both self and other.

pub const fn contains(&self, other: OFlag) -> bool

Returns true all of the flags in other are contained within self.

pub fn insert(&mut self, other: OFlag)

Inserts the specified flags in-place.

pub fn remove(&mut self, other: OFlag)

Removes the specified flags in-place.

pub fn toggle(&mut self, other: OFlag)

Toggles the specified flags in-place.

pub fn set(&mut self, other: OFlag, value: bool)

Inserts or removes the specified flags depending on the passed value.
