impl VarcFlags

pub const fn empty() -> VarcFlags

Returns an empty set of flags.

pub const fn all() -> VarcFlags

Returns the set containing all flags.

pub const fn bits(&self) -> u32

Returns the raw value of the flags currently stored.

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

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

pub const fn from_bits_truncate(bits: u32) -> VarcFlags

Convert from underlying bit representation, dropping any bits that do not correspond to flags.

pub const fn is_empty(&self) -> bool

Returns true if no flags are currently stored.

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

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

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

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

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

Inserts the specified flags in-place.

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

Removes the specified flags in-place.

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

Toggles the specified flags in-place.

pub const fn intersection(self, other: VarcFlags) -> VarcFlags

Returns the intersection between the flags in self and other.

Specifically, the returned set contains only the flags which are present in both self and other.

This is equivalent to using the & operator (e.g. ops::BitAnd), as in flags & other.

pub const fn union(self, other: VarcFlags) -> VarcFlags

Returns the union of between the flags in self and other.

Specifically, the returned set contains all flags which are present in either self or other, including any which are present in both.

This is equivalent to using the | operator (e.g. ops::BitOr), as in flags | other.

pub const fn difference(self, other: VarcFlags) -> VarcFlags

Returns the difference between the flags in self and other.

Specifically, the returned set contains all flags present in self, except for the ones present in other.

It is also conceptually equivalent to the “bit-clear” operation: flags & !other (and this syntax is also supported).

This is equivalent to using the - operator (e.g. ops::Sub), as in flags - other.
