Expand description

Trait that refreshes a token when it is expired

Required Methods§

Source

fn token_and_exp<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Option<(String, u64)>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Returns the token that is currently held within the instance of TokenCache, together with the expiry of that token as a u64 in seconds sine the Unix Epoch (1 Jan 1970).

Source

fn set_token<'life0, 'async_trait>( &'life0 self, token: String, exp: u64, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Updates the token to the value token.

Source

fn scope<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = String> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait,

Returns the intended scope for the current token.

Source

fn fetch_token<'life0, 'life1, 'async_trait>( &'life0 self, client: &'life1 Client, ) -> Pin<Box<dyn Future<Output = Result<(String, u64)>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Fetches and returns the token using the service account

Provided Methods§

Source

fn get<'life0, 'life1, 'async_trait>( &'life0 self, client: &'life1 Client, ) -> Pin<Box<dyn Future<Output = Result<String>> + Send + 'async_trait>>
where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Returns a valid, unexpired token. If the contained token is expired, it updates and returns the token.

Dyn Compatibility§

This trait is dyn compatible.

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