Implementations

impl PrimaryScrollAction

pub fn offset(self, m: ScrollMetrics) -> Option<f64>

pub fn apply_to<T>( self, target: &mut T, region: impl Fn(&T) -> Option<PrimaryScrollRegion>, set: impl FnOnce(&mut T, &PrimaryScrollRegion, f64), ) -> PrimaryScrollResult

where T: ?Sized,

Apply the action to target, whose primary region region reads: set moves it to the clamped offset only when that differs, and the result reports the region as it reads afterwards.

Trait Implementations

impl Clone for PrimaryScrollAction

fn clone(&self) -> PrimaryScrollAction

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PrimaryScrollAction

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl PartialEq for PrimaryScrollAction

fn eq(&self, other: &PrimaryScrollAction) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
