Methods

impl WriteFlags

pub fn empty() -> WriteFlags

Returns an empty set of flags.

pub fn all() -> WriteFlags

Returns the set containing all flags.

pub fn bits(&self) -> u32

Returns the raw value of the flags currently stored.

pub fn from_bits(bits: u32) -> Option<WriteFlags>

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

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: WriteFlags) -> bool

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

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

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

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

Inserts the specified flags in-place.

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

Removes the specified flags in-place.

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

Toggles the specified flags in-place.

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

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