Represents a single generic parameter within a GenericParams list.

Variants

Lifetime

A lifetime parameter, e.g., 'a or 'a: 'b + 'c.

Fields

name: Lifetime

The lifetime identifier (e.g., 'a).

bounds: Option<Cons<Colon, VerbatimUntil<Either<Comma, Gt>>>>

Optional lifetime bounds (e.g., : 'b + 'c).

Const

A const generic parameter, e.g., const N: usize = 10.

Fields

_const: KConst

The const keyword.

name: Ident

The name of the const parameter (e.g., N).

_colon: Colon

The colon separating the name and type.

typ: VerbatimUntil<Either<Comma, Gt, Eq>>

The type of the const parameter (e.g., usize).

default: Option<Cons<Eq, VerbatimUntil<Either<Comma, Gt>>>>

An optional default value (e.g., = 10).

Type

A type parameter, e.g., T: Trait = DefaultType.

Fields

name: Ident

The name of the type parameter (e.g., T).

bounds: Option<Bounds>

Optional type bounds (e.g., : Trait).

default: Option<Cons<Eq, VerbatimUntil<Either<Comma, Gt>>>>

An optional default type (e.g., = DefaultType).

Trait Implementations

impl Debug for GenericParam

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

Formats the value using the given formatter.

impl Parser for GenericParam

fn parser(tokens: &mut TokenIter) -> Result<Self>

The actual parsing function that must be implemented. This mutates the tokens iterator directly. It should not be called from user code except for implementing parsers itself and then only when the rules below are followed.

impl ToTokens for GenericParam

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

Write &self to the given TokenStream.

fn to_token_iter(&self) -> TokenIter

Convert &self into a TokenIter object.

fn into_token_iter(self) -> TokenIter

where Self: Sized,

Convert self into a TokenIter object.

fn to_token_stream(&self) -> TokenStream

Convert &self into a TokenStream object.

fn into_token_stream(self) -> TokenStream

where Self: Sized,

Convert self into a TokenStream object.

fn tokens_to_string(&self) -> String

Convert &self into a String object. This is mostly used in the test suite to compare the outputs. When the input is a &str then this parses it and returns a normalized String.
