pub const fn empty() -> Fstflags

Returns an empty set of flags

Returns the set containing all flags.

pub const fn bits(&self) -> u16

Returns the raw value of the flags currently stored.

Inserts the specified flags in-place.

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

Removes the specified flags in-place.

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

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

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