Enum VersionSource 

pub enum VersionSource {
    Manifest,
    Distribution,
}

Whether a publish target derives its release version from a package manifest the version guard can read, or has no manifest version by design — the capability the fail-closed guard keys on (version-source-fail-closed-nonrust).

The distinction is a function of the target’s Ecosystem, not its publish registry. A Rust/Node/Python package carries its version in a manifest (Cargo.toml/package.json/pyproject.toml) regardless of where it is published — a Rust crate repackaged for a Homebrew tap still reads its version from Cargo.toml, so it is Manifest. Keying on the registry instead would wrongly treat that crate (and a binary-distribution-only Rust repo) as versionless and refuse to derive a version that is plainly in the tree.

Variants

Manifest

The ecosystem carries the package version in a manifest (rust←Cargo.toml, node←package.json, python←pyproject.toml/setup.py). A resolved target of this class must expose a detected manifest version in facts; a resolved package with none is a detector failure that fails the guard closed (VersionResolveError::MissingManifestVersion) rather than silently skipping the version check (the fail-OPEN gap for manifest-versioned non-Rust ecosystems this model closes).

Distribution

No manifest version by design: the ecosystem’s version does not live in a tree manifest — a raw binary distribution (its version binds to the artifact it ships), or a VCS-tag-versioned go module (go.mod declares no version). Legitimately skipped by the version guard: there is no manifest to read a version from and none is expected.

Implementations

impl VersionSource

pub fn of(ecosystem: Ecosystem) -> Self

Classify a target by its Ecosystem (the ecosystem is the authority on whether a package’s version lives in a tree manifest).

Exhaustive over Ecosystem on purpose — a new ecosystem must make a deliberate manifest-vs-distribution choice here rather than default to a silent skip (which would re-open the fail-OPEN gap).
