* fix(datasource/rust-version): skip blank lines in manifests.txt `https://static.rust-lang.org/manifests.txt` ends with a trailing newline, so `response.body.split('\n')` always yields an empty final element. `parseManifestUrl('')` returns `null`, which triggered the `Failed to parse manifest URL` warning on every run. The warning then surfaces as a `Repository Problems` entry on the Dependency Dashboard for any repo with a rust-version-tracked dep (`rust-toolchain.toml`, or a custom-regex manager pointing at the `rust-version` datasource). Skip blank/whitespace-only lines silently; keep warning on genuinely malformed non-empty lines (covered by the existing "ignores unexpected URLs" test). * docs(datasource): condense comment Co-authored-by: RahulGautamSingh <rahultesnik@gmail.com> * Remove accidental newline --------- Co-authored-by: RahulGautamSingh <rahultesnik@gmail.com> Co-authored-by: Jamie Tanna <github@jamietanna.co.uk>
This datasource fetches available Rust compiler versions from the official Rust distribution infrastructure at https://static.rust-lang.org/manifests.txt.
How it works
The datasource retrieves version information from a single source file (manifests.txt) which contains chronological URLs to manifest files for all Rust releases.
Rather than fetching each individual manifest TOML file, version information is extracted directly from the URL patterns using regex parsing.
Supported Versions
The datasource only returns versions that correspond to specific Rust releases:
- Stable releases:
1.81.0,1.82.0, etc. - Beta releases:
1.83.0-beta.4,1.83.0-beta.5, etc. - Dated nightlies:
nightly-2025-11-23,nightly-2025-11-24, etc.
Version Extraction
Manifest URLs follow this pattern:
static.rust-lang.org/dist/YYYY-MM-DD/channel-rust-{identifier}.toml
Examples:
static.rust-lang.org/dist/2025-11-24/channel-rust-nightly.toml→ Version:nightly-2025-11-24static.rust-lang.org/dist/2024-10-17/channel-rust-1.82.0.toml→ Version:1.82.0static.rust-lang.org/dist/2025-01-15/channel-rust-1.83.0-beta.5.toml→ Version:1.83.0-beta.5
Release Timestamps
Release timestamps are derived from the date in the manifest URL and set to midnight UTC (YYYY-MM-DDTHH:MM:SS.000Z). This provides day-level precision for release timing.
Versioning Scheme
This datasource uses the rust-release-channel versioning scheme, which understands Rust's release channels, dated nightlies, and semantic versioning for stable and beta releases.
