Trait CredentialStore

    // Provided method
    fn lock_mutation(
        &self,
        target: &CredentialTarget,
    ) -> Result<Box<dyn CredentialMutation + Send + '_>, CredentialError> { ... }
}

Required Methods

fn check_available( &self, target: &CredentialTarget, ) -> Result<(), CredentialError>

fn exists(&self, target: &CredentialTarget) -> Result<bool, CredentialError>

Checks whether any native-vault entry exists without decoding it.

fn load( &self, target: &CredentialTarget, ) -> Result<Option<CredentialRecord>, CredentialError>

fn create( &self, target: &CredentialTarget, record: &CredentialRecord, ) -> Result<CredentialCreateOutcome, CredentialError>

fn delete(&self, target: &CredentialTarget) -> Result<bool, CredentialError>

fn delete_if_matches( &self, target: &CredentialTarget, expected: &CredentialRecord, ) -> Result<CredentialDeleteOutcome, CredentialError>

Deletes only the expected record. Implementations must serialize this comparison and deletion with credential saves for the same account.

Provided Methods

fn lock_mutation( &self, target: &CredentialTarget, ) -> Result<Box<dyn CredentialMutation + Send + '_>, CredentialError>

Dyn Compatibility

This trait is dyn compatible.

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