Struct OperationCapability 

pub struct OperationCapability {
    pub name: String,
    pub summary: String,
    pub availability: &'static str,
    pub requires: Vec<&'static str>,
}

One operation’s capability.

Fields

name: String

summary: String

availability: &'static str

One word, not two booleans.

The first draft carried supported and applicable, which is four bools on one struct and — more to the point — a shape a client has to know the meaning of. They are not redundant only in the archive case, and that is the case that matters: an operation can be understood and still not be performable, and collapsing the two into one word would either have to call archive “supported” (a lie a client acts on) or “unavailable” (which loses the fact that the request was at least well-formed). So one enum with three states, and a client reads a word rather than a pair of flags.

requires: Vec<&'static str>

What the request must also carry, besides a selection: target, kind, or nothing. A list rather than two bools, so adding a requirement is a new entry rather than a new field every client has to learn about.
