MemoryApprovalStore

Struct MemoryApprovalStore 

Source
pub struct MemoryApprovalStore { /* private fields */ }
Expand description

An in-process ApprovalStore. Cloning shares the state, so two coordinators over clones model two threads (or, with a fresh coordinator over the same store, a restart that kept the durable half). A real restart of the process forgets everything.

Implementations§

Trait Implementations§

Source§

impl ApprovalStore for MemoryApprovalStore

Source§

fn insert(&self, record: &ApprovalRecord) -> Result<(), StoreError>

Store a new request. Err(Exists) when the id is taken.
Source§

fn get(&self, id: &str) -> Result<Option<ApprovalRecord>, StoreError>

Source§

fn replace( &self, expected_revision: u64, record: &ApprovalRecord, ) -> Result<(), StoreError>

Replace the stored record with record only if the stored revision equals expected_revision; Err(Conflict) otherwise, Err(NotFound) for an unknown id.
Source§

fn list( &self, states: &[ApprovalState], ) -> Result<Vec<ApprovalRecord>, StoreError>

Every record in one of states, oldest first.
Source§

fn claim_nonce( &self, value: &str, expires_ms: u64, now_ms: u64, ) -> Result<bool, StoreError>

Remember value until expires_ms. Ok(true) when it was new, Ok(false) when it was already remembered (a replay). now_ms lets the store forget expired nonces.
