Provides variable resolution for expression evaluation.

Fields

env_context: &'a HashMap<String, String>

step_outputs: &'a HashMap<String, HashMap<String, String>>

matrix_combination: &'a Option<HashMap<String, Value>>

step_statuses: &'a HashMap<String, (String, String)>

Step ID → (outcome, conclusion) where values are “success”, “failure”, or “skipped”. outcome is the raw result before continue-on-error; conclusion is the effective result.

job_status: &'a str

Current job status for success()/failure()/cancelled() builtins: “success”, “failure”, or “cancelled”.

secrets_context: &'a HashMap<String, String>

Pre-resolved secrets for secrets.* context.

needs_context: &'a HashMap<String, HashMap<String, String>>

Job outputs from upstream jobs: job_name -> { output_key -> output_value }.

needs_results: &'a HashMap<String, String>

Job results from upstream jobs: job_name -> "success" | "failure" | "skipped".

user_env: &'a HashMap<String, String>

User-declared env vars only (merged workflow/job/step env: plus step-authored $GITHUB_ENV writes). env_context holds the union of these and runner-seeded vars; user_env is the user’s slice, consumed by toJSON(env) / bare env.

Invariant: every key inserted here must have been declared by the user (YAML env: at any scope, or written to $GITHUB_ENV by a step). Runner-seeded vars (GITHUB_, RUNNER_, INPUT_, WRKFLW_, CI, MATRIX_*) must NOT be inserted.
