Functions

after_resolution(execution)

Records end time for duration calculation.

Stores System.monotonic_time() in execution.acc[:ash_graphql][:end_time]. Always overwrites (captures the latest resolution end).

before_resolution(execution)

Records start time for duration calculation.

Stores System.monotonic_time() in execution.acc[:ash_graphql][:start_time]. Only sets the value if not already present (idempotent).

pipeline(pipeline, execution)

Conditionally adds the metadata injection phase to the pipeline.

If the schema has response_metadata enabled, prepends AshGraphql.Phase.InjectMetadata to process the captured timing data.
