Struct glutin::Icon

impl Icon

pub fn from_rgba( rgba: Vec<u8, Global>, 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(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.

Formats the value using the given formatter. Read more

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, Global>>> for Icon

Requires the icon_loading feature.

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

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 ==.

1.0.0 · source§

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.

impl<T> Any for Twhere T: 'static + ?Sized,

fn type_id(&self) -> TypeId

Gets the TypeId of self. Read more

impl<T> Borrow<T> for Twhere T: ?Sized,

fn borrow(&self) -> &T

Immutably borrows from an owned value. Read more

impl<T> BorrowMut<T> for Twhere T: ?Sized,

fn borrow_mut(&mut self) -> &mut T

Mutably borrows from an owned value. Read more

impl<T> Downcast for Twhere T: Any,

fn into_any(self: Box<T, Global>) -> Box<dyn Any, Global>

Convert Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.

fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>

Convert Rc<Trait> (where Trait: Downcast) to Rc<Any>. Rc<Any> can then be further downcast into Rc<ConcreteType> where ConcreteType implements Trait.

fn as_any(&self) -> &(dyn Any + 'static)

Convert &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s.

fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)

Convert &mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &mut Any’s vtable from &mut Trait’s.

impl<T> DowncastSync for Twhere T: Any + Send + Sync,

fn into_any_arc(self: Arc<T>) -> Arc<dyn Any + Send + Sync>

Convert Arc<Trait> (where Trait: Downcast) to Arc<Any>. Arc<Any> can then be further downcast into Arc<ConcreteType> where ConcreteType implements Trait.
