Trait Implementations

impl<T, L, C> Clone for GenericParam<T, L, C>where T: Clone, L: Clone, C: Clone,

fn clone(&self) -> GenericParam<T, L, C>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T, L, C> Debug for GenericParam<T, L, C>where T: Debug, L: Debug, C: Debug,

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

Formats the value using the given formatter.

impl<T> FromGenericParam for GenericParam<T, LifetimeDef, ConstParam>where T: FromTypeParam,

fn from_generic_param( param: &GenericParam ) -> Result<GenericParam<T, LifetimeDef, ConstParam>, Error>

impl<T> FromTypeParam for GenericParam<T, LifetimeDef, ConstParam>where T: FromTypeParam,

fn from_type_param( type_param: &TypeParam ) -> Result<GenericParam<T, LifetimeDef, ConstParam>, Error>

impl<T, L, C> GenericParamExt for GenericParam<T, L, C>

type TypeParam = T

The type this GenericParam uses to represent type params and their bounds

type LifetimeDef = L

type ConstParam = C

fn as_type_param(&self) -> Option<&T>

If this GenericParam is a type param, get the underlying value.

fn as_lifetime_def(&self) -> Option<&L>

If this GenericParam is a lifetime, get the underlying value.

fn as_const_param(&self) -> Option<&C>

If this GenericParam is a const param, get the underlying value.

impl<T, L, C> PartialEq<GenericParam<T, L, C>> for GenericParam<T, L, C>where T: PartialEq<T>, L: PartialEq<L>, C: PartialEq<C>,

fn eq(&self, other: &GenericParam<T, L, C>) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
