Form-token storage (RFC-007).

The consume operation must be atomic: a conditional UPDATE sets consumed_at only when the token is unconsumed, unexpired, and bindings match. The affected-row count drives TokenConsumeOutcome via crate::state::classify_token_consume.

Required Methods

fn insert_form_token( &self, record: FormTokenRecord, ) -> impl Future<Output = Result<(), StoreError>>

Insert a new form token record.

fn consume_form_token( &self, lookup_key: &LookupKey, subject: &TokenSubject, purpose: &str, bound_resource: Option<&str>, now: u64, ) -> impl Future<Output = Result<(TokenConsumeOutcome, Option<String>), StoreError>>

Attempt to atomically consume a form token.

The adapter must:

1. Run the conditional UPDATE (sets consumed_at).
2. If changed == 0, run a follow-up SELECT to classify why.
3. Call crate::state::classify_token_consume with the results.
4. Return the outcome plus any stored result_ref for replays.

fn set_token_result( &self, lookup_key: &LookupKey, result_ref: &str, ) -> impl Future<Output = Result<(), StoreError>>

Store a result reference on a consumed token for idempotency replay.

Dyn Compatibility

This trait is not dyn compatible.

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