Struct PartitionOrderViolation 

pub struct PartitionOrderViolation {
    pub attempted: u64,
    pub max_held: u64,
}

Error returned when a same-thread partition acquire violates ascending order. Phase H+ STRICT variant (D115).

The ascending-order protocol prevents AB/BA deadlocks between threads. When this error surfaces, the caller should defer the operation to wave-end (when no partitions are held) and retry. Vestigial (§7, D208–D211, 2026-05-16). The union-find ascending- order acquisition discipline that this represented is deleted: scheduling groups are user-declared + static and the wave engine acquires the whole touched-group set sorted upfront, so there is no incremental mid-wave acquisition that could violate ordering. This type is never constructed post-§7. It is retained only so SubscribeError::PartitionOrderViolation and the Err(_) match arms in graphrefly-operators compile unchanged (D211 minimal-churn); removing the type + those arms is a tracked downstream-churn follow-on (porting-deferred.md).

Trait Implementations

impl Clone for PartitionOrderViolation

fn clone(&self) -> PartitionOrderViolation

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PartitionOrderViolation

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

Formats the value using the given formatter.

impl Display for PartitionOrderViolation

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

Formats the value using the given formatter.

impl Error for PartitionOrderViolation

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<PartitionOrderViolation> for SubscribeError

fn from(source: PartitionOrderViolation) -> Self

Converts to this type from the input type.

impl PartialEq for PartitionOrderViolation

fn eq(&self, other: &PartitionOrderViolation) -> 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.
