{
    // Required methods
    fn unlock(&self) -> Result<Option<T>, KeyError>;
    fn persist(&self, material: &T) -> Result<(), KeyError>;
    fn forget(&self) -> Result<(), KeyError>;
    fn close(&self);

Required Methods

fn unlock(&self) -> Result<Option<T>, KeyError>

Called once at open; None when this device has never held T. Retain the unlocked persistence capability until close.

fn persist(&self, material: &T) -> Result<(), KeyError>

Keeps material, replacing what was kept.

fn forget(&self) -> Result<(), KeyError>

Removes what was kept; succeeds if nothing was kept.

fn close(&self)

Erase held memory after users finish; performs no persistence or IO.
