Trait TokenSource

    fn mint(&self) -> Result<MintedToken>;

    // Provided method
    fn describe(&self) -> String { ... }
}

Expand description

Anything that can produce a bearer token for the client.

Implementors must be Send + Sync because the client caches tokens behind a mutex and is shared across tasks.

Required Methods§

Source

fn mint(&self) -> Result<MintedToken>

Mint a fresh token. The client calls this lazily and caches the result until shortly before it expires, so this need not be cheap.

Provided Methods§

Source

fn describe(&self) -> String

A short, secret-free description for diagnostics and MCP transcripts. Must never contain key or token material — it may be logged or surfaced to a user. Defaults to the type’s shape.
