Enum Never 

pub enum Never {}

The uninhabited type with two structural jobs. As a phase menu, Step<Never> has no constructible Goto — a plain actor is a one-phase machine. As an outbound/offspring menu, it proves a layer sends or creates nothing. The law is the type, not a convention.

Trait Implementations

impl Clone for Never

fn clone(&self) -> Never

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Never

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

Formats the value using the given formatter.

impl PartialEq for Never

fn eq(&self, other: &Never) -> 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.

impl Copy for Never

impl Eq for Never

impl StructuralPartialEq for Never
