Enum KeyVerificationEvent 

pub enum KeyVerificationEvent<'a> {
    BeforeCandidate {
        depth: usize,
    },
    Verified(&'a dyn VerifyingKey),
}

Provider observations; only a successful leaf can supply key evidence.

Variants

BeforeCandidate

Admit another candidate dispatch; a previous terminal refusal stays terminal.

Fields

depth: usize

Nested composite depth, bounded by the hard candidate ceiling.

Verified(&'a dyn VerifyingKey)

This exact leaf returned a successful cryptographic verification.
