Convert from a bits value exactly.

pub fn from_name(name: &str) -> Option<Modifiers>

The bitwise or (|) of the bits in two flags values.

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

The bitwise or (|) of the bits in two flags values.

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

The intersection of a source flags value with the complement of a target flags value (&!).

The bitwise exclusive-or (^) of the bits in two flags values.

pub const fn complement(self) -> Modifiers

The bitwise negation (!) of the bits in a flags value, truncating the result.

impl Modifiers

Yield a set of contained flags values.

Each yielded flags value will correspond to a defined named flag. Any unknown bits will be yielded together as a final flags value.

This method is like iter, except only yields bits in contained named flags. Any unknown bits, or bits not corresponding to a contained flag will not be yielded.

impl Modifiers

pub fn from_input(input: &ButtonInput<KeyCode>) -> Modifiers

👎Deprecated since 0.4.0: Consider using Modifiers::from() instead.

Check modifier keys for any_pressed() to populate bit flags.
