Struct CopilotSession 

pub struct CopilotSession { /* private fields */ }

Manages a short-lived Copilot session token, auto-refreshing on expiry.

GitHub Copilot’s chat API requires a session token obtained by exchanging the long-lived OAuth device-flow token. Session tokens expire after ~30 minutes. This struct caches the active session and transparently refreshes it when needed.

Can also be initialized with an imported session token (no OAuth token). In that case, it will use the session token until it expires, then fail.

Implementations

impl CopilotSession

pub fn new(oauth_token: String) -> Self

Create a new session manager wrapping the given OAuth token.

pub fn from_session_token(session_token: String, expires_at: i64) -> Self

Create a session manager with an imported session token (no refresh capability).

pub async fn get_token(&self, http: &Client) -> Result<String>

Return a valid session token, exchanging or refreshing as needed.

Caches the token and only calls the exchange endpoint when the cached token is missing or within 60 seconds of expiry.
