Struct LoopCtx 

#[non_exhaustive]
pub struct LoopCtx<'a> {
    pub session_id: &'a SessionId,
    pub turn_id: Option<&'a TurnId>,
    pub point: MutationPoint,
    pub cancellation: Option<TurnCancellation>,
    pub emitter: &'a dyn EventEmitter,
}

Read-only context handed to a LoopMutator alongside the cursor.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

session_id: &'a SessionId

Session this mutation point belongs to.

turn_id: Option<&'a TurnId>

Turn the mutation is associated with, if any.

point: MutationPoint

Where in the loop the mutator is running.

cancellation: Option<TurnCancellation>

Cancellation handle for the active turn, if any.

emitter: &'a dyn EventEmitter

Sink for emitting events from the mutator (telemetry, progress).
