Trait WireKey 

pub trait WireKey: Sealed {
    // Required method
    fn resolve<M: Metadata + ?Sized>(self, metadata: &M) -> Option<usize>;
}

A wire reference — either a pre-resolved index (fast path) or a name (resolved against the context’s input map).

Lets get_wire accept either form so callers can hold an index when they have one and a name when they don’t, without needing two distinct method names.

Sealed: only the in-crate impls (usize, &str, String) are valid wire keys. External implementors are not permitted because the resolution semantics are tied to the context’s input layout.

Required Methods

fn resolve<M: Metadata + ?Sized>(self, metadata: &M) -> Option<usize>

Resolve to a wire index in metadata. Returns None when the key doesn’t match a wire on this context.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
