Enum CloneValidity 

pub enum CloneValidity {
    Cloneable,
    Invalid,
    PossiblyInvalid,
    Unknown,
}

Result of classifying a type for clone validity (see Type::clone_validity).

Variants

Cloneable

Every member is (or may be) an object — cloning is fine.

Invalid

Every member is definitely a non-object — cloning is an error.

PossiblyInvalid

Some members are non-objects, some are objects — cloning may be an error.

Unknown

Empty/unknown type — no diagnostic.

Trait Implementations

impl Clone for CloneValidity

fn clone(&self) -> CloneValidity

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for CloneValidity

impl Debug for CloneValidity

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

Formats the value using the given formatter.

impl Eq for CloneValidity

impl PartialEq for CloneValidity

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