The `fail_on_warning` parameter determines how to treat warnings encountered during parsing. Any problems encountered during are stored until the whole string has been parsed. Any problem during parsing falls into two catgeories: + +* Fatal error preventing further parsing or processing of the SDP +* Warning which don't block further processing of the SDP + +Warnings will be for example unknown parameters in attributes. Setting `fail_on_warning` to `true` makes most sense during development, when you want to be aware of all potential problems. In production `fail_on_warning` is expected to be `false`. + +`parse_sdp()` returns either an `SdpSession` struct ([code](https://github.com/mozilla/webrtc-sdp/blob/master/src/lib.rs#L137)) which contains all the parsed information. Or in case a fatal error was encountered (or if `fail_on_warning` was set to `true` and any warnings were encountered) an `SdpParserError` ([code](https://github.com/mozilla/webrtc-sdp/blob/master/src/error.rs#L117)) will be returned as a `Result`. + +## Examples + +The [file parser](https://github.com/mozilla/webrtc-sdp/blob/master/examples/file_parser.rs) in the webrtc-sdp package gives you an easy example of how to invoke the webrtc-sdp parser. + +## Contributing + +As the Travis CI runs are checking for code formating and clippy warnings please run the following commands locally, before submitting a Pull Request. + +If you haven't clippy and Rust format installed already you add them like this: +``` +rustup component add rustfmt-preview +rustup component add clippy +``` + +Check with clippy for warnings in the code: +``` +cargo clippy +``` + +And format all of the code according to Rust code style convention: +``` +cargo fmt --all +``` + +## Fuzzing + +Install cargo-fuzz like this: +``` +cargo install cargo-fuzz +``` + +With rust nightly you can start fuzzing like this: +``` +cargo fuzz run fuzz_target_parse_sdp +``` + +## License + +Licensed under [MPL-2.0](https://www.mozilla.org/MPL/2.0/) |
