Enum Safety 

pub enum Safety {
    Safe,
    Unsafe(u8),
}

How a rule participates in search.

Variants

Safe

Never loses provability — applied eagerly, no branch point.

Unsafe(u8)

May not lead to a proof — forks the search; higher priority tried first.

Trait Implementations

impl Clone for Safety

fn clone(&self) -> Safety

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Safety

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

Formats the value using the given formatter.

impl PartialEq for Safety

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