Expand description

A way to load URLs from a data source.

Included implementations:

  • PathBuf, loads data from disk using the PathBuf as working directory.

Associated Types

type Load: Future<Output = Result<Vec<u8>, Self::Error>> + Send[src]

A future returned when calling load.

type Wait: Future<Output = Result<(), Self::Error>> + Send[src]

A future returned when calling wait.

type Error: 'static + Error + Send + Sync[src]

Error returned by the loader when the request failed.

Required methods

fn load(&self, url: impl AsRef<str>) -> Self::Load[src]

Asynchronously load a resource located at the given url

fn wait(&self, url: impl AsRef<str>) -> Self::Wait[src]

Wait for a resource to be modified externally.
