Struct CustomCursor 

pub struct CustomCursor(pub Arc<dyn CustomCursorProvider>);

Use a custom image as a cursor (mouse pointer).

Is guaranteed to be cheap to clone.

Platform-specific

Web: Some browsers have limits on cursor sizes usually at 128x128.

Example

use winit_core::cursor::CustomCursorSource;

let w = 10;
let h = 10;
let rgba = vec![255; (w * h * 4) as usize];

#[cfg(not(target_family = "wasm"))]
let source = CustomCursorSource::from_rgba(rgba, w, h, w / 2, h / 2).unwrap();

#[cfg(target_family = "wasm")]
let source = CustomCursorSource::Url {
    url: String::from("http://localhost:3000/cursor.png"),
    hotspot_x: 0,
    hotspot_y: 0,
};

if let Ok(custom_cursor) = event_loop.create_custom_cursor(source) {
    window.set_cursor(custom_cursor.clone().into());
}

Tuple Fields

0: Arc<dyn CustomCursorProvider>

Methods from Deref<Target = dyn CustomCursorProvider>

pub fn cast_ref<T>(&self) -> Option<&T>

where T: CustomCursorProvider,

Downcast to the backend concrete type.

Returns None if the object was not from that backend.

Trait Implementations

impl Clone for CustomCursor

fn clone(&self) -> CustomCursor

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CustomCursor

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

Formats the value using the given formatter.

impl Deref for CustomCursor

type Target = dyn CustomCursorProvider

The resulting type after dereferencing.

fn deref(&self) -> &<CustomCursor as Deref>::Target

Dereferences the value.

impl From<CustomCursor> for Cursor

fn from(custom: CustomCursor) -> Cursor

Converts to this type from the input type.

impl Hash for CustomCursor

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 CustomCursor

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