Struct ScrollState

pub struct ScrollState {
    pub scroll_position: LogicalPosition,
}

Fields

scroll_position: LogicalPosition

Amount in pixel that the current node is scrolled

Implementations

impl ScrollState

pub fn get(&self) -> LogicalPosition

Return the current position of the scroll state

pub fn add(&mut self, x: f32, y: f32, child_rect: &LogicalRect)

Add a scroll X / Y onto the existing scroll state

pub fn set(&mut self, x: f32, y: f32, child_rect: &LogicalRect)

Set the scroll state to a new position

Trait Implementations

impl Clone for ScrollState

fn clone(&self) -> ScrollState

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ScrollState

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

Formats the value using the given formatter.

impl Default for ScrollState

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for ScrollState

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

impl PartialOrd for ScrollState

fn partial_cmp(&self, other: &ScrollState) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
