Struct ScrollOffset 

#[repr(transparent)]
pub struct ScrollOffset(pub LogicalPosition);

A scroll offset, i.e. how far a scroll container’s content has been moved UP/LEFT relative to its scrollport.

Distinct from a position so that “add the scroll” and “add a position” cannot be confused, and so the two very different sums — ancestors-only vs self-and-ancestors — are at least visible at the call site.

Tuple Fields

0: LogicalPosition

Implementations

impl ScrollOffset

pub const fn zero() -> Self

The zero offset (nothing scrolled).

pub const fn new(x: f32, y: f32) -> Self

Build an offset from raw components.

pub const fn get(self) -> LogicalPosition

The raw offset.

pub const fn plus(self, other: Self) -> Self

Accumulate another container’s offset into this one.

impl Ord for ScrollOffset

fn cmp(&self, other: &ScrollOffset) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

where Self: Sized,

Restrict a value to a certain interval.

fn clamp_to<R>(self, range: R) -> Self

where Self: Sized, R: ClampBounds<Self>,

🔬This is a nightly-only experimental API. (clamp_to)

Restrict a value to a certain range.

impl PartialEq for ScrollOffset

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

Equality operator ==.

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