Provided methods

Read data from the underlying storage into input writer.

Write data from input reader to the underlying storage.

Invoke the stat operation on the specified path.

Delete will invoke the delete operation.

Behavior
  • Delete is an idempotent operation, it’s safe to call Delete on the same path multiple times.
  • Delete will return Ok(()) if the path is deleted successfully or not exist.

Implementations on Foreign Types

All functions in Accessor only requires &self, so it’s safe to implement Accessor for Arc<dyn Accessor>.
