This is a nom-based SDP parser. It can parse and reserialize and is currently optimized for a very small wasm footprint (hence the use of ufmt). You don't need reserialization? Just build with --no-default-features.

Why?

There is already mozilla's webrtc-sdp, sdp from webrtc.rs and sdp-types, which are all very good, why make another? This is still very much a "for fun" project, so don't mind me!

Objectives

With this parser we try to implement a wasm-friendly, low-copy and high-level-nom parser.

WASM-Friendly

By using wee and ufmt we try to achieve a small binary size. Further Debug-printing is a feature that can be disabled. Further concrete wasm-related work is on the horizon.

low copy

Zero copy seems a bit out of reach but this parser tries to enable as much as possible without actually copying over the content of the sdp. This is achieved by reading any string into a Cow and only optionally creating a 'static copy of the content.

functional high-level parser-combinators

SDP is a weird standard, there is no container format specification other than that lines start with a char followed by =. Basically every line follows it's own rules. Therefore every line has its own parser like in this example:

/// Email `e=<email-address>`
pub struct EmailAddress<'a>(pub Cow<'a, str>);

/// "e=email@example.com"
pub fn email_address_line(input: &str) -> IResult<&str, EmailAddress> {
    line("e=", wsf(map(cowify(read_string), EmailAddress)))(input)
}
