Methods

impl SpecialDerives

pub const PARTIAL_EQ: SpecialDerives

pub const EQ: SpecialDerives

pub const COPY: SpecialDerives

pub const fn empty() -> SpecialDerives

Returns an empty set of flags

pub const fn is_empty(&self) -> bool

Returns true if no flags are currently stored.

pub const fn is_all(&self) -> bool

Returns true if all flags are currently set.

pub const fn intersects(&self, other: SpecialDerives) -> bool

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

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

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