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-2025-11-24`
|
|
- `static.rust-lang.org/dist/2024-10-17/channel-rust-1.82.0.toml`
|
|
→ Version: `1.82.0`
|
|
- `static.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.
