Struct ScrollDelta 

pub struct ScrollDelta {
    pub dx: i32,
    pub dy: i32,
}

Direction and magnitude of a scroll event, in platform “ticks” (typically one notch of a physical scroll wheel). Positive dy scrolls content downward (i.e. moves the viewport up); positive dx scrolls right.

Fields

dx: i32

dy: i32

Implementations

impl ScrollDelta

pub const fn new(dx: i32, dy: i32) -> ScrollDelta

pub const fn vertical(dy: i32) -> ScrollDelta

pub const fn horizontal(dx: i32) -> ScrollDelta

Trait Implementations

impl Clone for ScrollDelta

fn clone(&self) -> ScrollDelta

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ScrollDelta

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

Formats the value using the given formatter.

impl Default for ScrollDelta

fn default() -> ScrollDelta

Returns the “default value” for a type.

impl Hash for ScrollDelta

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

where __H: Hasher,

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 ScrollDelta

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