Trait CredentialMutation 

pub trait CredentialMutation: Send {
    // Required methods
    fn exists(&self) -> Result<bool, CredentialError>;
    fn load(&self) -> Result<Option<CredentialRecord>, CredentialError>;
    fn create(

}

Required Methods

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

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

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

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

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