Enum Auth 

pub enum Auth {
    ClientCredentials {
        client_id: String,
        client_secret: String,
    },
    Bearer {
        token: String,
    },
    Password {
        user: String,
        pass: String,
    },
    RefreshToken {
        refresh_token: String,
        client_id: String,
    },
}

How the SDK authenticates. Configure once when building the client.

The Debug impl redacts the secret-bearing fields (client_secret, pass, token, refresh_token) so a stray {:?} in logs or an error report can’t leak credentials.

Variants

ClientCredentials

Server-to-server OAuth2 client_credentials grant against /oauth/token, resolved once at connect into a bearer token. Requires an OAuth2 application (client id/secret); see the Authentication guide for the current availability caveat.

Fields

client_id: String

OAuth2 application client id.

client_secret: String

OAuth2 application client secret.

Bearer

A bearer token you already hold (e.g. the access token from a PKCE flow).

Fields

token: String

The bearer access token, sent as Authorization: Bearer <token>.

Password

OAuth2 password grant against /oauth/token (resolved once at connect).

Fields

user: String

Resource-owner username.

pass: String

Resource-owner password.

RefreshToken

A refresh token from the Authorization Code + PKCE flow, exchanged once at connect into a bearer token.

Unlike the TypeScript/Go SDKs there is no transparent background refresh — the resolved access token is used for the client’s lifetime. Because refresh tokens are rotated on every use, the token passed here is consumed at connect and the newly issued one is discarded; callers that need long-lived rotation should drive it manually via mgr.auth.token("refresh_token", …) and rebuild the client (or use Auth::Bearer).

Fields

refresh_token: String

The refresh token to exchange for an access token.

client_id: String

OAuth2 application client id the refresh token was issued to.
