Trait Implementations

impl<F> CredentialProvider for FnProvider<F>

where F: Fn(&CredentialRequest<'_>) -> Result<Option<Credential>, Error> + Send + Sync,

fn credential<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, request: &'life1 CredentialRequest<'life2>, ) -> Pin<Box<dyn Future<Output = Result<Option<Credential>, Error>> + Send + 'async_trait>>

where 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait, FnProvider<F>: 'async_trait,

Resolve the credential for request, or Ok(None) to defer to ambient auth. An Err aborts the operation (e.g. the vault was unreachable).

impl<F> Debug for FnProvider<F>

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

Formats the value using the given formatter.
