Enum Acquisition 

pub enum Acquisition {
    Granted,
    Waiting,
    Deadlock(Deadlock),
}

Available on crate feature std only.

The outcome of a deadlock-aware request.

Unlike try_acquire, request does not just fail on conflict — it records the wait and tells the caller whether to proceed, suspend, or abort.

Variants

Granted

The lock was granted; the transaction holds it and may proceed.

Waiting

The lock is held incompatibly. The transaction is now registered as waiting; the caller should suspend it and retry request later (for example after a release). No deadlock was found.

Deadlock(Deadlock)

Granting the wait would close a cycle in the wait-for graph. The caller must abort the named victim (with release_all) to break the deadlock. The victim may be the requesting transaction itself or another transaction in the cycle.

Trait Implementations

impl Clone for Acquisition

fn clone(&self) -> Acquisition

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Acquisition

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Eq for Acquisition

impl PartialEq for Acquisition

fn eq(&self, other: &Acquisition) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
