Enum tame_oauth::gcp::TokenProviderWrapperInner

pub enum TokenProviderWrapperInner {
    EndUser(EndUserCredentialsInner),
    Metadata(MetadataServerProviderInner),
    ServiceAccount(ServiceAccountProviderInner),
}

Wrapper around the different providers that are supported. Implements both TokenProvider and IdTokenProvider. Should not be used directly as it is not cached. Use TokenProviderWrapper instead.

Variants

EndUser(EndUserCredentialsInner)

Metadata(MetadataServerProviderInner)

ServiceAccount(ServiceAccountProviderInner)

Implementations

impl TokenProviderWrapperInner

pub fn get_default_provider() -> Result<Option<Self>, Error>

Get a TokenProvider following the “Google Default Credentials” flow. Returns a uncached token provider, use TokenProviderWrapper::get_default_provider instead.

pub fn kind(&self) -> &'static str

Gets the kind of token provider

pub fn is_service_account_provider(&self) -> bool

pub fn is_metadata_server_provider(&self) -> bool

pub fn is_end_user_credentials_provider(&self) -> bool

Trait Implementations

impl Debug for TokenProviderWrapperInner

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl IdTokenProvider for TokenProviderWrapperInner

fn get_id_token(&self, audience: &str) -> Result<IdTokenOrRequest, Error>

Attempts to retrieve an id token that can be used when communicating via IAP etc.

fn get_id_token_with_access_token<S>( &self, audience: &str, response: AccessTokenResponse<S> ) -> Result<IdTokenRequest, Error>

where S: AsRef<[u8]>,

Some token sources require a access token to be used to generte a id token. If get_id_token returns a AccessTokenResponse, this method should be called.

fn parse_id_token_response<S>( &self, hash: u64, response: Response<S> ) -> Result<IdToken, Error>

where S: AsRef<[u8]>,

Once a IdTokenResponse has been received for an id token request, call this method to deserialize the token.

impl TokenProvider for TokenProviderWrapperInner

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> + Clone, 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> + Clone,

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.
