Trait ockam::ParserFragment

pub trait ParserFragment<W> where
    W: Worker, {
    fn ids(&self) -> Vec<ProtocolId>;

    fn parse(
        &self, 
        _state: &mut W, 
        _ctx: &mut Context, 
        _routed: &Routed<Any>, 
        _msg: ProtocolPayload
    ) -> Result<bool> { ... }
}

A parser for a protocol fragment

Protocols are implemented as separate structures, wrapped in a carrier type. Because Rust can’t have a function return different types from a function, each protocol message (here called “Fragment”) needs to be handled by a separate parser.

Required methods

fn ids(&self) -> Vec<ProtocolId>

Return the set of ProtocolIDs this parser can handle

Provided methods

fn parse(
    &self,
    _state: &mut W,
    _ctx: &mut Context,
    _routed: &Routed<Any>,
    _msg: ProtocolPayload
) -> Result<bool>

Parse an incoming message for a particular worker

Implementors

    W: Worker,
    F: Fn(&mut W, &mut Context, Routed<StreamWorkerCmd>) -> Result<bool>,
