Enum TurnPhase 

#[non_exhaustive]
pub enum TurnPhase {
    Received,
    Interpreted,
    Reduced,
    Executing,
    Committed,
    Composed,
    Delivered,
    Failed,
}

Persisted phase marker of a turn, for crash recovery (spec §23.1).

The pipeline grows phases, so downstream matches need a wildcard arm.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Received

Input accepted and persisted.

Interpreted

A plan was accepted.

Reduced

A reduction plan exists.

Executing

Commands are executing.

Committed

Commands committed.

Composed

Response blocks composed and persisted.

Delivered

Response delivered.

Failed

The turn failed.

Implementations

impl TurnPhase

pub fn is_terminal(self) -> bool

Returns true for Delivered and Failed.

pub fn effects_may_exist(self) -> bool

Returns true once commands may have executed; recovery must resume by idempotency key instead of re-interpreting (spec §23.1).

Trait Implementations

impl Clone for TurnPhase

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.
