Module partial 

Partial build target resolution for split/merge CI fan-out.

Partial-build target resolution — resolves which build targets to include when running in split mode.

Enums

PartialTarget

A resolved partial build target filter.

Functions

detect_host_target

Detect the host target triple via rustc -vV.

detect_rustc_version

Detect the rustc release version string via rustc -vV.

find_runtime_target

Best-effort host->triple fuzzy matcher for --single-target.

host_buildable_targets

Partition configured targets into (buildable, skipped) for the given host triple, per the --host-targets rule.

host_is_apple

true when the host triple is an Apple/Darwin host (and can therefore build Apple targets in addition to everything else).

host_is_windows

true when the host triple is a Windows host (and can therefore build windows-msvc targets in addition to everything else).

host_targets_skip_message

Render the single loud-log line emitted when --host-targets skips configured targets, naming the host OS, the count, and — grouped by reason — which triples were skipped and why. Returns None when nothing was skipped.

host_targets_skip_reasons

Group skipped triples by their host constraint and render <triples> (<reason>) clauses joined by ; , preserving the apple → windows order so the message is deterministic. Each triple is attributed to the constraint that caused it to be skipped.

resolve_host_target

Process-env form of resolve_host_target_with_env.

resolve_host_target_with_env

Resolve the effective host target triple for --single-target.

resolve_partial_target

Resolve the partial build target from environment variables and config.

resolve_partial_target_with_env

Env-injectable form of resolve_partial_target. Production wires up ProcessEnvSource; tests inject a MapEnvSource to drive the env-var branches without mutating the process env.

suggest_runner

Suggest a GitHub Actions runner for a given OS.
