Required Methods

fn create_writable_with_options( &mut self, options: &CreateWritableOptions, ) -> impl Future<Output = Result<Self::WritableFileStreamT, Self::Error>>

fn read(&self) -> impl Future<Output = Result<Vec<u8>, Self::Error>>

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
