Struct tame_oauth::gcp::ServiceAccountAccess

pub struct ServiceAccountAccess { /* fields omitted */ }

A token provider for a GCP service account.

Methods

impl ServiceAccountAccess

pub fn new(info: ServiceAccountInfo) -> Result<Self, Error>

Creates a new ServiceAccountAccess given the provided service account info. This can fail if the private key is encoded correctly.

pub 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.

Note that the scopes are not sorted or in any other way manipulated, so any modifications to them will require a new token to be requested.

pub 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 store it in the cache so that future API requests don't have to retrieve a new token, until it expires.
