Struct Scrollbar 

pub struct Scrollbar { /* private fields */ }

Immutable semantic input for one finite-viewport position indicator.

Lengths and positions use caller-defined content units. They may be rows, columns, items, or another uniform unit, provided all three values use the same unit. Rendering clamps position to the last origin at which the viewport remains within the content.

Implementations

impl Scrollbar

pub const fn new( orientation: ScrollbarOrientation, content_length: usize, viewport_length: usize, ) -> Self

Creates a scrollbar at the beginning of its content.

pub const fn position(self, position: usize) -> Self

Replaces the requested viewport origin.

The presentation clamps an out-of-range value after accounting for the current content and viewport lengths.

pub const fn orientation(&self) -> ScrollbarOrientation

pub const fn content_length(&self) -> usize

pub const fn viewport_length(&self) -> usize

pub const fn get_position(&self) -> usize

Trait Implementations

impl Clone for Scrollbar

fn clone(&self) -> Scrollbar

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Scrollbar

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

Formats the value using the given formatter.

impl Hash for Scrollbar

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Scrollbar

fn eq(&self, other: &Scrollbar) -> 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.
