Enum GenericArgument

pub enum GenericArgument {
    Lifetime(Lifetime),
    Type(Type),
    Binding(Binding),
    Const(Expr),
}

An individual generic argument, like 'a, T, or Item = T.

This type is available if Syn is built with the "derive" or "full" feature.

Variants

Lifetime(Lifetime)

A lifetime argument.

Type(Type)

A type argument.

Binding(Binding)

A binding (equality constraint) on an associated type: the Item = u8 in Iterator<Item = u8>.

Const(Expr)

A const expression. Must be inside of a block.

NOTE: Identity expressions are represented as Type arguments, as they are indistinguishable syntactically.

Trait Implementations

impl Clone for GenericArgument

fn clone(&self) -> GenericArgument

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for GenericArgument

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

Formats the value using the given formatter.

impl Hash for GenericArgument

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 PartialEq for GenericArgument

fn eq(&self, other: &GenericArgument) -> 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 Synom for GenericArgument

fn parse(i: Cursor<'_>) -> PResult<'_, Self>

fn description() -> Option<&'static str>

impl ToTokens for GenericArgument

fn to_tokens(&self, tokens: &mut Tokens)

Write self to the given Tokens.

fn into_tokens(self) -> Tokens

where Self: Sized,

Convert self directly into a Tokens object.

impl Eq for GenericArgument
