Trait SecretProvider 

pub trait SecretProvider: Send + Sync {
    // Required method
    fn get_secret<'life0, 'async_trait>(
        &'life0 self,
        key: SecretKey,
    ) -> Pin<Box<dyn Future<Output = Option<String>> + Send + 'async_trait>>
       where Self: 'async_trait,
             'life0: 'async_trait;
}

A source of secrets used by core provider selection and execution.

Implementations should treat missing secrets as None and should not panic.

Note: this is async to support implementations backed by secure storage.

Required Methods

fn get_secret<'life0, 'async_trait>( &'life0 self, key: SecretKey, ) -> Pin<Box<dyn Future<Output = Option<String>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Retrieve a secret by key.

Implementations should return None if the secret does not exist or is unavailable.
