Struct ImplVarTraitItemMappings 

pub struct ImplVarTraitItemMappings<'db> { /* private fields */ }

A mapping of an impl var’s trait items to concrete items

Implementations

impl ImplVarTraitItemMappings<'_>

pub fn is_empty(&self) -> bool

Returns true if the impl var has no mappings.

Trait Implementations

impl<'db> Clone for ImplVarTraitItemMappings<'db>

fn clone(&self) -> ImplVarTraitItemMappings<'db>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'db> Debug for ImplVarTraitItemMappings<'db>

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

Formats the value using the given formatter.

impl<'db> Default for ImplVarTraitItemMappings<'db>

fn default() -> ImplVarTraitItemMappings<'db>

Returns the “default value” for a type.

impl<'db> Hash for ImplVarTraitItemMappings<'db>

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<'db> PartialEq for ImplVarTraitItemMappings<'db>

fn eq(&self, other: &ImplVarTraitItemMappings<'db>) -> 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.
