[]Struct nix::sys::mman::MapFlags

pub struct MapFlags { /* fields omitted */ }

Additional parameters for mmap().

Methods

impl MapFlags

pub const MAP_FILE: MapFlags

Compatibility flag. Ignored.

pub const MAP_SHARED: MapFlags

Share this mapping. Mutually exclusive with MAP_PRIVATE.

pub const MAP_PRIVATE: MapFlags

Create a private copy-on-write mapping. Mutually exclusive with MAP_SHARED.

pub const MAP_FIXED: MapFlags

Place the mapping at exactly the address specified in addr.

pub const MAP_ANON: MapFlags

Synonym for MAP_ANONYMOUS.

pub const MAP_ANONYMOUS: MapFlags

The mapping is not backed by any file.

pub const MAP_32BIT: MapFlags

Put the mapping into the first 2GB of the process address space.

pub const MAP_GROWSDOWN: MapFlags

Used for stacks; indicates to the kernel that the mapping should extend downward in memory.

pub const MAP_DENYWRITE: MapFlags

Compatibility flag. Ignored.

pub const MAP_EXECUTABLE: MapFlags

Compatibility flag. Ignored.

pub const MAP_LOCKED: MapFlags

Mark the mmaped region to be locked in the same way as mlock(2).

pub const MAP_NORESERVE: MapFlags

Do not reserve swap space for this mapping.

This was removed in FreeBSD 11.

pub const MAP_POPULATE: MapFlags

Populate page tables for a mapping.

pub const MAP_NONBLOCK: MapFlags

Only meaningful when used with MAP_POPULATE. Don't perform read-ahead.

pub const MAP_HUGETLB: MapFlags

Allocate the mapping using "huge pages."

pub const MAP_STACK: MapFlags

Region grows down, like a stack.

pub const fn empty() -> MapFlags

Returns an empty set of flags

pub const fn all() -> MapFlags

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<MapFlags>

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) -> MapFlags

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: MapFlags) -> bool

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

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

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

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

Inserts the specified flags in-place.

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

Removes the specified flags in-place.

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

Toggles the specified flags in-place.

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

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