Implementations

impl Provenance

pub fn from_env() -> Self

Create provenance from environment variables set by xtask.

Expected env vars:

• FACET_SHOWCASE_COMMIT: full git commit SHA
• FACET_SHOWCASE_COMMIT_SHORT: short git commit SHA
• FACET_SHOWCASE_TIMESTAMP: ISO 8601 timestamp
• FACET_SHOWCASE_RUSTC_VERSION: rustc version string
• FACET_SHOWCASE_GITHUB_REPO: GitHub repo (e.g., “facet-rs/facet”)
• FACET_SHOWCASE_SOURCE_FILE: relative path to source file

pub fn github_source_url(&self) -> Option<String>

Generate a GitHub URL to the source file at the exact commit.

pub fn has_info(&self) -> bool

Check if we have meaningful provenance info.

Trait Implementations

impl Clone for Provenance

fn clone(&self) -> Provenance

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Provenance

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Provenance

fn default() -> Provenance

Returns the “default value” for a type.
