Source 
pub async fn fetch_pr_diff(
    base_url: &str,

    repo: &str,
    pr_number: u64,
    token: &str,
) -> Result<DiffResult, RsGuardError>
Expand description

Fetches the diff for a GitHub Pull Request.

Sends a GET request to the GitHub API with the application/vnd.github.v3.diff accept header. Automatically retries on transient failures (429, 5xx, timeouts).

The base_url is validated against an allowlist before any request is made, preventing Authorization headers from being sent to untrusted hosts.

§Arguments

  • base_url — GitHub API base URL (e.g. "https://api.github.com").
  • owner — Repository owner.
  • repo — Repository name.
  • pr_number — Pull request number.
  • token — GitHub authentication token.

§Errors

Returns RsGuardError::Config if base_url is not allowlisted, RsGuardError::GitHubApi on HTTP errors, RsGuardError::EmptyDiff if the diff is empty, RsGuardError::InvalidDiffContent if the response is not a valid diff, or RsGuardError::DiffTooLarge if the diff exceeds size limits.
