Enum ChainOutcome 

pub enum ChainOutcome {
    Pass,
    Fail {
        reason: String,
    },
    CryptoUnimplemented,
}

Outcome of verify_chain.

Variants

Pass

All structural checks pass. The chain is well-formed and the cv= integrity rules hold. Use the chain’s accumulated Authentication-Results for downstream DMARC.

Fail

The chain has at least one violation. reason is a short human-readable explanation suitable for the arc=fail reason="…" authres field per RFC 8601.

Fields

reason: String

Short fail reason for AuthResults output.

CryptoUnimplemented

👎Deprecated since 1.1.0:

verify_chain_with_crypto now performs cryptographic verification; this variant is no longer returned

Structural layer passed; cryptographic layer not yet implemented. Returned by verify_chain_with_crypto only when it is invoked from a path that requested structural-only (none of the current public APIs return this — it is retained for compatibility with 1.0 callers that pattern-matched on it).

Trait Implementations

impl Clone for ChainOutcome

fn clone(&self) -> ChainOutcome

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ChainOutcome

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for ChainOutcome

fn eq(&self, other: &ChainOutcome) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
