SqliteExecutionNonceStore

chio_store_sqlite::execution_nonce_store

Struct SqliteExecutionNonceStore 

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

SQLite-backed replay-prevention store for execution nonces.

Implementations§

Source§

impl SqliteExecutionNonceStore

Source

pub fn open( path: impl AsRef<Path>, ) -> Result<Self, SqliteExecutionNonceStoreError>

Open the store at the given path. Creates the parent directory if needed.

Source

pub fn open_in_memory() -> Result<Self, SqliteExecutionNonceStoreError>

Open an in-memory store for tests.

Source

pub fn try_reserve( &self, nonce_id: &str, now: i64, expires_at: i64, ) -> Result<bool, SqliteExecutionNonceStoreError>

Reserve a nonce id. Shared code path for the trait impl and tests – takes an explicit expires_at for caller-controlled retention (the trait method uses now + RETENTION_GRACE_SECS).

Trait Implementations§

Source§

impl ExecutionNonceStore for SqliteExecutionNonceStore

Source§

fn reserve(&self, nonce_id: &str) -> Result<bool, KernelError>

Attempt to reserve (consume) the given nonce identifier. Read more
Source§

fn reserve_until( &self, nonce_id: &str, nonce_expires_at: i64, ) -> Result<bool, KernelError>

Reserve a nonce while telling the store when the nonce stops being cryptographically valid. Durable implementations (SQLite, remote KV stores) MUST retain the consumed marker until at least nonce_expires_at so replay protection covers the nonce’s full validity window. Read more

fn is_consumed(&self, nonce_id: &str) -> Result<bool, KernelError>
