axum-range

HTTP range responses for axum.

Fully generic, supports any body implementing the RangeBody trait.

Any type implementing both AsyncRead and AsyncSeekStart can be used the KnownSize adapter struct. There is also special cased support for tokio::fs::File, see the KnownSize::file method.

AsyncSeekStart is a trait defined by this crate which only allows seeking from the start of a file. It is automatically implemented for any type implementing AsyncSeek.
