Required Methods§

source

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

Contains other button.

Note, other can contains one or many buttons. In case of there’s many buttons, returns true if at least one button of other is contained in this.

source

fn contains_ref(&self, other: &Self) -> bool

Contains other button. Same as Self::contains but not taking ownership of other.

source

fn any(&self) -> bool

Contains any buttons, opposite of Self::is_empty.

source

fn is_empty(&self) -> bool

There’s no buttons

source

fn Left() -> Self

source

fn Right() -> Self

source

fn Up() -> Self

source

fn Down() -> Self

source

fn B() -> Self

source

fn A() -> Self

Provided Methods§

source

fn left(&self) -> bool

Contains left button.
