Trait PinStorage 

pub trait PinStorage: Send + Sync {
    // Required methods
    fn load_pin_state(&self) -> Result<PinState, StatusCode>;
    fn save_pin_state(&self, state: &PinState) -> Result<(), StatusCode>;
}

Trait for PIN storage backends

This trait is implemented by storage backends that can persist PIN state. The soft-fido2 library calls these methods when PIN state changes.

Required Methods

fn load_pin_state(&self) -> Result<PinState, StatusCode>

Load PIN state from storage

Returns default state if no state is stored.

fn save_pin_state(&self, state: &PinState) -> Result<(), StatusCode>

Save PIN state to storage

Trait Implementations

impl PinStorage for Box<dyn PinStorage>

fn load_pin_state(&self) -> Result<PinState, StatusCode>

Load PIN state from storage

fn save_pin_state(&self, state: &PinState) -> Result<(), StatusCode>

Save PIN state to storage

Dyn Compatibility

This trait is dyn compatible.

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