pub struct NullSecretsBackend;

No-op secrets backend used when no real backend is configured.

Returns Err("no secrets backend configured") for every call. Suitable for deployments that don’t use raw transport or managed credentials.

Trait Implementations

impl SecretsBackend for NullSecretsBackend

fn resolve_tls_profile<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, name: &'life1 str, _tenant: &'life2 str, ) -> Pin<Box<dyn Future<Output = Result<TlsHandle>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Resolve a named TLS profile to an opaque handle. name uses scheme-routing: vault://prod/tls/kafka, file://kafka-prod.

fn get_credential<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, name: &'life1 str, _tenant: &'life2 str, ) -> Pin<Box<dyn Future<Output = Result<CredentialHandle>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Resolve a named credential.

fn get_string<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, name: &'life1 str, _tenant: &'life2 str, ) -> Pin<Box<dyn Future<Output = Result<SecretString>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Read a named secret as a zeroizing string.

fn subscribe( &self, _name: &str, _tenant: &str, ) -> Pin<Box<dyn Stream<Item = RotationEvent> + Send>>

Subscribe to rotation events. Implementations that don’t support rotation return an empty stream.
