Struct InMemoryLock 

pub struct InMemoryLock { /* private fields */ }

In-memory Lock backed by a Mutex<{ locked, waiters }>.

The std Mutex is held only for the brief state check/update — never across an .await — so it never blocks the executor. Acquisition returns a future that, while the lock is held, registers the task’s waker and yields Pending; unlock wakes all registered waiters so they re-contend (one wins, the rest re-register). Runtime-agnostic: no dependency on any async runtime, matching the rest of the crate’s RPITIT async surface.

Implementations

impl InMemoryLock

pub fn new() -> Self

Trait Implementations

impl Default for InMemoryLock

fn default() -> Self

Returns the “default value” for a type.

impl Lock for InMemoryLock

fn lock(&self) -> impl Future<Output = Result<(), LockError>> + Send + '_

Acquire the lock, awaiting until it becomes available.

async fn try_lock(&self) -> Result<bool, LockError>

Try to acquire the lock without waiting.

async fn unlock(&self) -> Result<(), LockError>

Release the lock, waking any waiters so they can re-contend.
