A Rocket responder for types implementing the AsyncRead + AsyncSeek traits, such as files and rocket::futures::io::Cursor, that will respond to range requests with a 206 Partial Content response. The Content-Type can optionally be inferred by taking a sample of bytes from the beginning of the stream, or given manually. An Accept-Ranges: bytes header will be sent in all responses to notify browsers that range requests are supported for the resource.
This supports both single and multipart/byterange requests. https://tools.ietf.org/html/rfc7233
Add this to your dependencies.

Serving a file from the disk
```rust
extern crate rocket; use rocketseekstream::SeekStream;
fn home<'a>() -> std::io::Result
async fn main() { match rocket::build().mount("/", routes![home]).launch().await { Ok(_) => (), Err(e) => { eprintln!("Rocket stopped unexpectedly. (Error {})", e); } }; } ```
Serving an in memory buffer
```rust
fn cursor<'a>() -> SeekStream<'a> { let bytes = &includebytes!("./flymetothe_moon.webm")[..]; let len = bytes.len(); let stream = std::io::Cursor::new(bytes);
SeekStream::with_opts(stream, len as u64, "video/webm")
} ```
Use cargo run --example server to run the example. run examples/download.sh to download the media it depends on using youtube-dl.
I've compared the output of the Golang stdlib http router's multipart response to what I output here and it looks about the same except for a small difference in whitespace.
