Implementations

impl LangItemEnum

pub fn from_lang_items(self, lang_items: &LangItems) -> Option<LangItemTarget>

pub fn from_symbol(symbol: &Symbol) -> Option<LangItemEnum>

Trait Implementations

impl Clone for LangItemEnum

fn clone(&self) -> LangItemEnum

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LangItemEnum

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

Formats the value using the given formatter.

impl Hash for LangItemEnum

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

where __H: Hasher,

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 LangItemEnum

fn eq(&self, other: &LangItemEnum) -> 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 LangItemEnum

impl Eq for LangItemEnum

impl StructuralPartialEq for LangItemEnum
