pub struct DiscreteScrollState { /* private fields */ }Expand description
Helper for accumulating and converting pixel/line scrolls into and integer delta between discrete options.
Implementations§
Source§impl DiscreteScrollState
impl DiscreteScrollState
Sourcepub fn rate_limit(self, rate_limit: Option<Duration>) -> Self
pub fn rate_limit(self, rate_limit: Option<Duration>) -> Self
Set a rate limit. If set, a call to update() will only not produce
values other than 1, -1, or 0 and a non-zero return value will not
occur more frequently than this duration.
Sourcepub fn reset(&mut self)
pub fn reset(&mut self)
Reset, clearing any acculuated scroll events that haven’t been converted to discrete events yet.
Sourcepub fn update(&mut self, delta: ScrollDelta) -> DiscreteScrollDelta
pub fn update(&mut self, delta: ScrollDelta) -> DiscreteScrollDelta
Accumulate delta with a timer
