Methods

impl 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: Flags) -> bool

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

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

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

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

Inserts the specified flags in-place.
