A resource is a reference to binary data, for example images. They can be accessible on the file system or embedded in the resulting binary. Or they might be URLs to a web server and a downloaded is necessary before they can be used. cbindgen:prefix-with-name

None

A resource that does not represent any data.

Implementations

impl ImageInner

pub fn render_to_buffer(
    &self,
    _target_size_for_scalable_source: Option<IntSize>
) -> Option<SharedImageBuffer>

Return or render the image into a buffer

target_size_for_scalable_source is the size to use if the image is scalable.

Returns None if the image can’t be rendered in a buffer

Trait Implementations

impl Clone for ImageInner

fn clone(&self) -> ImageInner

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ImageInner

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

Formats the value using the given formatter.

impl Default for ImageInner

fn default() -> Self

Returns the “default value” for a type.

impl<'a> From<&'a Image> for &'a ImageInner

fn from(other: &'a Image) -> Self

Converts to this type from the input type.

impl From<ImageInner> for Image

fn from(original: ImageInner) -> Image

Converts to this type from the input type.

impl PartialEq<ImageInner> for ImageInner

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