crate sflowrt-rs-flow

a crate for working with sFlow-RT's flow construct. see sFlow-RT Doc: Defining Flows. in particular, the sflowrt_flow::key::key_parser module contains the beginnings of a parser for sFlow-RT's key definition dsl, implemented via the nom parser combinator library. the framework for the language is in good shape, but there are many flow keys provided by sFlow-RT that i have not yet implemented; the same is true for the key functions.

crate sflowrt-rs-cli

a crate the contains a cli + repl for the sflowrt-rs project. currently, it is just a repl with a single command, parse-key, for interactively running the key definition dsl langauge parser (implemented in the sflowrt-rs-flow crate).

a small demo of using parse-key (with a little output formatting):

$ cargo run sflowrt-rs-cli
sflowrt-rs-cli〉parse-key ip6destination,group:[country:ip6source]:trusted:bad:unknown
KeyDefinition { keys: [
    KeyName(Ip6Destination),
    KeyFunction(Group(GroupKeyFunction {
        key: KeyFunction(Country(CountryKeyFunction {
            arg: "ip6source"
        })),
        group_names: ["trusted", "bad", "unknown"]
    }))
] }

why?

i'm trying to more fully immerse myself in rust programming. i wanted a toy project that would allow me to focus on learning rust (as well as nom); i'm already pretty familiar with sFlow-RT and thought building a parser for its flow key definition language would be fun. it has been!
