Implementations

impl MapFlags[src]

pub const MAP_FILE: MapFlags[src]

Compatibility flag. Ignored.

pub const MAP_SHARED: MapFlags[src]

Share this mapping. Mutually exclusive with MAP_PRIVATE.

Compatibility flag. Ignored.

Make use of 2GB huge page (must be supported by the system)

pub const MAP_HUGE_16GB: MapFlags[src]

Make use of 16GB huge page (must be supported by the system)

Region grows down, like a stack.

pub const fn empty() -> MapFlags[src]

Returns an empty set of flags

pub const fn all() -> MapFlags[src]

Returns the set containing all flags.

pub const fn bits(&self) -> c_int[src]

Returns the raw value of the flags currently stored.

pub fn from_bits(bits: c_int) -> Option<MapFlags>[src]

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[src]

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

pub const unsafe fn from_bits_unchecked(bits: c_int) -> MapFlags[src]

Convert from underlying bit representation, preserving all bits (even those not corresponding to a defined flag).

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

Returns true if no flags are currently stored.

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

Returns true if all flags are currently set.

pub const fn intersects(&self, other: MapFlags) -> bool[src]

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

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

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

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

Inserts the specified flags in-place.

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

Removes the specified flags in-place.

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

Toggles the specified flags in-place.

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

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