Module task 

Task types, submission parameters, and the TypedTask trait.

This module defines the data structures that flow through the scheduler: TaskSubmission for enqueuing work, TaskRecord for in-flight tasks, TaskHistoryRecord for completed/failed results, and TypedTask for strongly-typed task payloads with built-in serialization.

Structs

TaskError

Reported by the executor on failure.

TaskHistoryRecord

A task that has completed or permanently failed.

TaskRecord

A task in the active queue (pending, running, or paused).

TaskResult

TaskSubmission

Parameters for submitting a new task.

TypeStats

Aggregate statistics for a task type from history.

Enums

HistoryStatus

Terminal state of a task in history.

ParentResolution

Resolution of a parent task after a child completes or fails.

SubmitOutcome

Result of a task submission attempt.

TaskLookup

Unified lookup result for querying a task by its dedup inputs.

TaskStatus

Lifecycle state of a task in the active queue.

Constants

MAX_PAYLOAD_BYTES

Maximum payload size in bytes (1 MiB).

Traits

TypedTask

A strongly-typed task that bundles serialization, task type name, and default IO estimates.

Functions

generate_dedup_key

Generate a dedup key by hashing the task type and payload.
