Struct NoneEvent

pub struct NoneEvent;

NoneEvent is a semi-private event struct that is used to allow the Initializer trait implementations to provide a simple API to initialise a new machine.

Using this struct, the following works:

let sm = TurnStile::new(Locked); // => TurnStile<Locked, None>

Otherwise, we’d need to provide type annotations (using any available events) for every machine invocation:

let sm: TurnStile<Locked, Push> = TurnStile::new(Locked); // => TurnStile<Locked, None>

In practice, you will never deal with this struct, as it’s used as a concrete type that is swapped for the None option at compile time.

Trait Implementations

impl Clone for NoneEvent

fn clone(&self) -> NoneEvent

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for NoneEvent

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

Formats the value using the given formatter.

impl PartialEq for NoneEvent

fn eq(&self, other: &NoneEvent) -> 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.
