Enum TokenState 

pub enum TokenState {
    Booting,
    Idle,
    Authenticated,
    WaitingForTouch,
    Signing,
    Error,
}

All the operating states the token can be in.

Variants

Booting

Just powered on, peripherals coming up. Yellow LED blinks.

Idle

Idle, waiting for a host command. Green solid.

Authenticated

PIN session is active and the user can request a signature. Green slow pulse.

WaitingForTouch

A Sign request is pending and the user must press the touch button within TOUCH_TIMEOUT_MS. Yellow solid.

Signing

Touch confirmed, signing in progress. Both LEDs alternate briefly.

Error

An error occurred. Green LED fast-blinks for ERROR_DISPLAY_MS then returns to TokenState::Idle.

Implementations

impl TokenState

pub const fn initial() -> Self

Initial state at power-on.

pub const fn led_pattern(self) -> LedPattern

LED pattern associated with this state.

pub const fn on_event(self, event: Event) -> Self

Apply an event and return the next state.

Events that do not match any transition for the current state are ignored. The function returns the state unchanged. This is the conservative behaviour, equivalent to a default: do nothing arm. The dispatch loop is free to fire SessionEnded repeatedly without risking pathological transitions for example.

Trait Implementations

impl Clone for TokenState

fn clone(&self) -> TokenState

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for TokenState

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for TokenState

fn eq(&self, other: &TokenState) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
