impl TokenProvider for MetadataServerProvider

fn get_token_with_subject<'a, S, I, T>(
    &self,
    subject: Option<T>,
    scopes: I
) -> Result<TokenOrRequest, Error> where
    S: AsRef<str> + 'a,
    I: IntoIterator<Item = &'a S>,
    T: Into<String>, 

Like TokenProvider::get_token, but allows the JWT “subject” to be passed in.

fn parse_token_response<S>(
    &self,
    _hash: u64,
    response: Response<S>
) -> Result<Token, Error> where
    S: AsRef<[u8]>, 

Once a response has been received for a token request, call this method to deserialize the token (and potentially store it in a local cache for reuse until it expires).

fn get_token<'a, S, I>(&self, scopes: I) -> Result<TokenOrRequest, Error> where
    S: AsRef<str> + 'a,
    I: IntoIterator<Item = &'a S>, 

Attempts to retrieve a token that can be used in an API request, if we haven’t already retrieved a token for the specified scopes, or the token has expired, an HTTP request is returned that can be used to retrieve a token.
