Match

Enum Match 

Source
pub enum Match<'a, A> {
    Exact(&'a A),
    Prefix,
    NoMatch,
}
Expand description

The outcome of resolving a pending key buffer with SequenceKeymap::lookup.

Resolution is deliberately not the name here: that word is reserved by keymap-core for raw-byte passthrough. This is purely the table-view answer — whether the keys are an exact hit, a prefix, or a miss — leaving “should I wait?” to the caller.

The three variants are exhaustive on purpose: a pure trie lookup has no other outcome, and timeout (jj-style) handling lives in the caller, not in this result. So this enum is not #[non_exhaustive] — callers can and should match all three arms with the compiler checking coverage.

Variants§

§

Exact(&'a A)

The keys are a complete binding, resolving to this action.

§

Prefix

The keys are a proper prefix of at least one longer binding.

§

NoMatch

The keys are not on any binding path.
