Struct InMemoryEip3009NonceStore 

pub struct InMemoryEip3009NonceStore { /* private fields */ }

Process-local single-use EIP-3009 nonce store.

Backed by Mutex<Eip3009NonceMap>. Suitable for tests and explicitly ephemeral single-process deployments. No durable implementation is provided in-tree; production callers must supply durable replay protection before broadcast.

Implementations

impl InMemoryEip3009NonceStore

pub fn new() -> Self

Build a fresh store with the default hard capacity.

pub fn with_max_entries(max_entries: usize) -> Self

Build a fresh store with a custom hard capacity.

Trait Implementations

impl Default for InMemoryEip3009NonceStore

fn default() -> Self

Returns the “default value” for a type.

impl Eip3009NonceStore for InMemoryEip3009NonceStore

fn record_if_fresh( &self, from_address: &str, nonce: &str, retain_until_unix_seconds: u64, ) -> Result<NonceOutcome, SettlementError>

Record (from_address, nonce) for replay detection.

fn gc_expired(&self, now_unix_seconds: u64) -> Result<usize, SettlementError>

Sweep entries whose retention bound is below now_unix_seconds.

fn len(&self) -> Result<usize, SettlementError>

Number of currently retained entries. Used by tests and metrics.

fn is_empty(&self) -> Result<bool, SettlementError>

True if no entries are retained.
