Struct winit::Icon

pub struct Icon { /* private fields */ }

An icon used for the window titlebar, taskbar, etc.

Enabling the icon_loading feature provides you with several convenience methods for creating an Icon from any format supported by the image crate.

Implementations

impl Icon

pub fn from_rgba(rgba: Vec<u8>, width: u32, height: u32) -> Result<Self, BadIcon>

Creates an Icon from 32bpp RGBA data.

The length of rgba must be divisible by 4, and width * height must equal rgba.len() / 4. Otherwise, this will return a BadIcon error.

pub fn from_path<P: AsRef<Path>>(path: P) -> ImageResult<Self>

Loads an Icon from the path of an image on the filesystem.

Requires the icon_loading feature.

pub fn from_reader<R: BufRead + Seek>(
    reader: R,
    format: ImageFormat
) -> ImageResult<Self>

Loads an Icon from anything implementing BufRead and Seek.

Requires the icon_loading feature.

pub fn from_bytes(bytes: &[u8]) -> ImageResult<Self>

Loads an Icon from the unprocessed bytes of an image file. Uses heuristics to determine format.

Requires the icon_loading feature.

pub fn from_bytes_with_format(
    bytes: &[u8],
    format: ImageFormat
) -> ImageResult<Self>

Loads an Icon from the unprocessed bytes of an image.

Requires the icon_loading feature.

Trait Implementations

impl Clone for Icon

fn clone(&self) -> Icon

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Icon

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

Formats the value using the given formatter.

impl From<DynamicImage> for Icon

Requires the icon_loading feature.

fn from(image: DynamicImage) -> Self

Converts to this type from the input type.

impl From<ImageBuffer<Rgba<u8>, Vec<u8, Global>>> for Icon

Requires the icon_loading feature.

fn from(buf: RgbaImage) -> Self

Converts to this type from the input type.

impl PartialEq<Icon> for Icon

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
