Module output_refs 

Task output reference processing.

Handles detection and resolution of #TaskOutputRef structs in task JSON. These structs are produced by CUE when tasks reference another task’s stdout, stderr, or exitCode fields.

Processing Pipeline

1. CUE evaluates tasks.tmpdir.stdout → { cuenvOutputRef: true, cuenvTask: "tmpdir", cuenvOutput: "stdout" }
2. process_output_refs walks raw JSON, replaces ref objects with placeholder strings
3. Task deserialization sees plain strings in args/env (Vec<String>)
4. OutputRefResolver::resolve replaces placeholder strings with actual values before execution

Structs

OutputRefResolver

Context for resolving task output reference placeholders at runtime.

TaskOutputRef

A parsed task output reference.

Enums

TaskOutputField

Which output field of a task is being referenced.

Functions

has_output_refs

Returns true if any string in args or env contains an output ref placeholder.

parse_passthrough

Parse a passthrough placeholder string, returning the host var name.

process_output_refs

Process task output references in raw JSON before deserialization.

Type Aliases

OutputRefDep

A dependency pair: (task_that_references, task_being_referenced).
