Trait TokenFetcher 

pub trait TokenFetcher {
    // Required method
    async fn fetch_token(&self, provider: &str) -> Result<BrokerToken, String>;

    // Provided method
    async fn fetch_credential(
        &self,
        cred: &CredentialRef,
    ) -> Result<BrokerToken, TokenFetchError> { ... }
}

“Get a fresh access token from somewhere.” Abstracted so the cache/resolve logic is unit-testable without real HTTP. The real impl is BrokerClient.

Required Methods

async fn fetch_token(&self, provider: &str) -> Result<BrokerToken, String>

Provided Methods

async fn fetch_credential( &self, cred: &CredentialRef, ) -> Result<BrokerToken, TokenFetchError>

Account-addressed fetch. Default: the default slot goes through fetch_token; a named slot is unsupported (never silently served from the default slot).

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
