pub const MAP_GROWSDOWN: MapFlags

MAP_GROWSDOWN: MapFlags = MapFlags{bits: libc::MAP_GROWSDOWN,}

MAP_LOCKED: MapFlags = MapFlags{bits: libc::MAP_LOCKED,}

pub const MAP_NORESERVE: MapFlags

MAP_NORESERVE: MapFlags = MapFlags{bits: libc::MAP_NORESERVE,}

Do not reserve swap space for this mapping.

This was removed in FreeBSD 11.

MAP_POPULATE: MapFlags = MapFlags{bits: libc::MAP_POPULATE,}

Populate page tables for a mapping.

pub const MAP_NONBLOCK: MapFlags

MAP_NONBLOCK: MapFlags = MapFlags{bits: libc::MAP_NONBLOCK,}

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

MAP_HUGETLB: MapFlags = MapFlags{bits: libc::MAP_HUGETLB,}

Allocate the mapping using "huge pages."

pub const MAP_STACK: MapFlags

MAP_STACK: MapFlags = MapFlags{bits: libc::MAP_STACK,}

Region grows down, like a stack.

pub fn empty() -> MapFlags

Returns an empty set of flags.

pub fn all() -> MapFlags

Returns the set containing all flags.

pub 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 fn from_bits_truncate(bits: c_int) -> MapFlags

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

pub fn is_empty(&self) -> bool

Returns true if no flags are currently stored.

pub fn is_all(&self) -> bool

Returns true if all flags are currently set.

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

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

pub 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.
