Trait SeekableReader 

pub trait SeekableReader:
    AsyncRead
    + AsyncSeek
    + Send
    + Unpin { }

An async reader that can also seek.

Seeking is what lets a stream answer Range requests, so a FileSource::SeekableStream needs both capabilities. Implemented automatically for anything that is AsyncRead + AsyncSeek + Send + Unpin, so you never implement it yourself.

Dyn Compatibility

This trait is dyn compatible.

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