Trait Implementations

impl Clone for GenericParams

fn clone(&self) -> GenericParams

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for GenericParams

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

Formats the value using the given formatter.

impl Hash for GenericParams

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 Index<Idx<LifetimeParamData>> for GenericParams

type Output = LifetimeParamData

The returned type after indexing.

fn index(&self, index: LocalLifetimeParamId) -> &LifetimeParamData

Performs the indexing (container[index]) operation.

impl Index<Idx<TypeOrConstParamData>> for GenericParams

type Output = TypeOrConstParamData

The returned type after indexing.

fn index(&self, index: LocalTypeOrConstParamId) -> &TypeOrConstParamData

Performs the indexing (container[index]) operation.

impl PartialEq for GenericParams

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