Module cache 

Task-level caching glue between the executor, cuenv_cas, and cuenv_vcs.

This module is responsible for:

1. Building the cuenv_cas::Action envelope for a task: a deterministic summary of everything that affects the task’s outputs.
2. Querying the cuenv_cas::ActionCache for a previous result.
3. Materializing cached outputs back into the workspace on a hit.
4. Persisting outputs and metadata after a successful execution on a miss.

Structs

BuildActionInput

Inputs to build_action.

RecordInput

Inputs to record grouped to keep call sites self-documenting.

TaskCacheConfig

Bundle of caching infrastructure used by the task executor.

Functions

build_action

effective_policy

Returns the effective task cache policy.

lookup

Query the action cache for a previous result.

materialize_hit

Materialize a cache hit’s outputs into workdir.

record

Persist a successful execution to the cache.
