Struct 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<Icon, 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>(path: P) -> Result<Icon, ImageError>

where P: AsRef<Path>,

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

Requires the icon_loading feature.

pub fn from_reader<R>( reader: R, format: ImageFormat, ) -> Result<Icon, ImageError>

where R: BufRead + Seek,

Loads an Icon from anything implementing BufRead and Seek.

Requires the icon_loading feature.

pub fn from_bytes(bytes: &[u8]) -> Result<Icon, ImageError>

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, ) -> Result<Icon, ImageError>

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 duplicate 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<(), Error>

Formats the value using the given formatter.

impl From<DynamicImage> for Icon

Requires the icon_loading feature.

fn from(image: DynamicImage) -> Icon

Converts to this type from the input type.

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

Requires the icon_loading feature.

fn from(buf: ImageBuffer<Rgba<u8>, Vec<u8>>) -> Icon

Converts to this type from the input type.

impl PartialEq for Icon

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