Enum Rejection 

pub enum Rejection {
    Conflict,
    CiFailure,
    SafetyViolation {
        strategy: &'static str,
        violation: Violation,
    },
    DependencyEjection {
        on: u64,
    },
    AlreadyLanded,
}

Why a change left the queue without merging.

Variants

Conflict

Merge produced a first-class conflict; author must resolve and resubmit.

CiFailure

CI failed for this change on its speculative state.

SafetyViolation

A strategy resolved, but its output edits the speculative state beyond what the change proposed: silently reverted or injected lines. Treated like a conflict — evicted first-class, never landed, never blocking the train — but reported separately because the author’s change may be fine and the strategy at fault.

Fields

strategy: &'static str

The strategy whose resolution violated the invariant.

violation: Violation

The unattributable lines, as evidence for escalation.

DependencyEjection

Ejected because it (transitively) declared a dependency on a change whose combined build failed. Not a verdict on this change itself: resubmit once the dependency is fixed.

Fields

on: u64

The CI-failing change this one depends on.

AlreadyLanded

A change with this identity::change_identity already landed through this queue: the resubmission — typically the same edit rebased after the train rewrote the tip — is refused without re-merging, so it cannot land twice.

Trait Implementations

impl Clone for Rejection

fn clone(&self) -> Rejection

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Rejection

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

Formats the value using the given formatter.

impl PartialEq for Rejection

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