Struct GithubClient 

pub struct GithubClient { /* private fields */ }

Sync GitHub Releases API client.

Constructed with an explicit base URL (for test injection via mockito) and an optional bearer token. Does not read environment variables in the constructor — use from_env() for that.

Implementations

impl GithubClient

pub fn new(base_url: &str, user_agent: &str, token: Option<String>) -> Self

Create a client with an explicit token (or None for unauthenticated).

Tests use this constructor directly to avoid touching process-global env state.

pub fn from_env(base_url: &str, user_agent: &str) -> Self

Create a client reading auth from the environment.

Precedence: GITHUB_TOKEN wins when both are set, matching gh CLI’s default non-enterprise behavior.

pub fn latest_release_tag(&self, org: &str, repo: &str) -> Result<String, Error>

Fetch the latest (most recently published, non-draft) release tag.

Uses the list endpoint (/repos/{org}/{repo}/releases) rather than /releases/latest so that pre-release tags are visible.

pub fn release_asset_body( &self, org: &str, repo: &str, tag: &str, ) -> Result<(u64, Box<dyn Read + Send>), Error>

Stream the first .tar.gz asset for a given release tag.

Returns (content_length, reader). The reader is the raw HTTP body; the caller wraps it in a progress bar and hands it to tarball::extract_safe.
