Converts to this type from the input type.

impl From<LifetimeParam> for GenericParam

fn from(e: LifetimeParam) -> GenericParam

Converts to this type from the input type.

impl From<TypeParam> for GenericParam

fn from(e: TypeParam) -> GenericParam

Converts to this type from the input type.

impl Hash for GenericParam

Available on crate feature extra-traits only.

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)

impl Parse for GenericParam

Available on crate feature parsing only.

fn parse(input: ParseStream<'_>) -> Result<Self>

impl PartialEq for GenericParam

Available on crate feature extra-traits only.

fn eq(&self, other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

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