Struct ImageRequest 

pub struct ImageRequest { /* private fields */ }

The image to load, and the largest size in pixels it is drawn at.

Implementations

impl ImageRequest

pub fn new(url: impl Into<Arc<str>>) -> Self

An image at url: http://, https://, file:// or a file path.

pub fn bytes(key: impl Into<Arc<str>>, bytes: impl Into<Arc<[u8]>>) -> Self

An image in encoded bytes (PNG, JPEG, WebP or GIF) the app already holds. key names it in the memory cache; one key is one image.

pub fn max_size(self, width: u32, height: u32) -> Self

Decodes the image no larger than width × height pixels, keeping its aspect ratio: a thumbnail of a large photo holds a thumbnail’s memory. Pass the size it is drawn at, in device pixels.

pub fn or_max_size(self, width: u32, height: u32) -> Self

max_size, unless the request already has one: a composable that knows the size it draws at fills it in, and an app that asked for a size keeps it.
