Struct DoubleTap 

pub struct DoubleTap { /* private fields */ }

A double tap: two presses, the first no longer than DoubleTap::tap_time, the second going down within DoubleTap::window of the first coming up.

Fires on the second press unless made with DoubleTap::on_release.

The fields are private so the only double taps that exist are ones the evaluator can time.

Implementations

impl DoubleTap

pub fn new(tap_time: f32, window: f32) -> Option<Self>

A double tap that fires on the second press, or None unless both times are finite and positive.

pub const fn on_release(self) -> Self

This double tap, firing on the second press’s release instead of on the press — and only if that press lasted at most DoubleTap::tap_time, as the first had to. See the module docs.

pub const fn fires_on_release(self) -> bool

Whether it fires on the second press’s release rather than the press.

pub const fn tap_time(self) -> f32

The longest the first press can last, in seconds — and, for a double tap made with DoubleTap::on_release, the second.

pub const fn window(self) -> f32

The longest gap between the first release and the second press, in seconds.
