pub enum AssetSourceId<'a> {
    Default,
    Name(CowArc<'a, str>),
}
Expand description

A reference to an “asset source”, which maps to an AssetReader and/or AssetWriter.

  • AssetSourceId::Default corresponds to “default asset paths” that don’t specify a source: /path/to/asset.png
  • AssetSourceId::Name corresponds to asset paths that do specify a source: remote://path/to/asset.png, where remote is the name.

Variants§

§

Default

The default asset source.

§

Name(CowArc<'a, str>)

A non-default named asset source.

Implementations§

source§

impl<'a> AssetSourceId<'a>

source

pub fn new(source: Option<impl Into<CowArc<'a, str>>>) -> AssetSourceId<'a>

Creates a new AssetSourceId

source

pub fn as_str(&self) -> Option<&str>

Returns None if this is AssetSourceId::Default and Some containing the name if this is AssetSourceId::Name.

source

pub fn into_owned(self) -> AssetSourceId<'static>

If this is not already an owned / static id, create one. Otherwise, it will return itself (with a static lifetime).

source

pub fn clone_owned(&self) -> AssetSourceId<'static>

Clones into an owned [AssetSourceId<'static>]. This is equivalent to .clone().into_owned().
