fn empty() -> NIFlags
Returns an empty set of flags.
fn all() -> NIFlags
Returns the set containing all flags.
fn bits(&self) -> i32
Returns the raw value of the flags currently stored.
fn from_bits(bits: i32) -> Option<NIFlags>
Convert from underlying bit representation, unless that representation contains bits that do not correspond to a flag.
fn from_bits_truncate(bits: i32) -> NIFlags
Convert from underlying bit representation, dropping any bits that do not correspond to flags.
fn is_empty(&self) -> bool
Returns true
if no flags are currently stored.
fn is_all(&self) -> bool
Returns true
if all flags are currently set.
fn intersects(&self, other: NIFlags) -> bool
Returns true
if there are flags common to both self
and other
.
fn contains(&self, other: NIFlags) -> bool
Returns true
all of the flags in other
are contained within self
.
fn insert(&mut self, other: NIFlags)
Inserts the specified flags in-place.
fn remove(&mut self, other: NIFlags)
Removes the specified flags in-place.
fn toggle(&mut self, other: NIFlags)
Toggles the specified flags in-place.
fn set(&mut self, other: NIFlags, value: bool)
Inserts or removes the specified flags depending on the passed value.
