Enum LangInterfaceItem 

pub enum LangInterfaceItem {
    Drop,
    Clone,
    Handle,
    OpEq,
    OpCmp,
}

Lang-item name applied to an interface declaration.

ADR-0080 retired Copy from this enum: posture is declared on the type with the copy keyword, queried via @ownership(T), and never dispatched, so it is no longer an interface.

Variants

Drop

Drop — values may carry custom destructors.

Clone

Clone — values support a clone(self) method producing an owned duplicate.

Handle

Handle — wraps a non-copyable resource that’s still allowed to move out of let bindings (linear-type carve-out).

OpEq

Eq — drives == operator desugaring.

OpCmp

Ord — drives </<=/>/>= operator desugaring.

Implementations

impl LangInterfaceItem

pub fn name(self) -> &'static str

The string the prelude uses inside @lang("…") for this item.

pub fn from_str(s: &str) -> Option<Self>

pub fn all() -> &'static [LangInterfaceItem]

Trait Implementations

impl Clone for LangInterfaceItem

fn clone(&self) -> LangInterfaceItem

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LangInterfaceItem

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

Formats the value using the given formatter.

impl Hash for LangInterfaceItem

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for LangInterfaceItem

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