Represents the kind of a struct definition.

Variants

Struct

A regular struct with named fields, e.g., struct Foo { bar: u32 }.

Fields

clauses: Option<WhereClauses>

Optional where clauses.

fields: BraceGroupContaining<CommaDelimitedVec<StructField>>

The fields enclosed in braces {}.

TupleStruct

A tuple struct, e.g., struct Foo(u32, String);.

Fields

fields: ParenthesisGroupContaining<CommaDelimitedVec<TupleField>>

The fields enclosed in parentheses ().

clauses: Option<WhereClauses>

Optional where clauses.

semi: Semi

The trailing semicolon ;.

UnitStruct

A unit struct, e.g., struct Foo;.

Fields

clauses: Option<WhereClauses>

Optional where clauses.

semi: Semi

The trailing semicolon ;.

Trait Implementations

impl Debug for StructKind

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

Formats the value using the given formatter.

impl Parser for StructKind

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 StructKind

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

Write &self to the given TokenStream.

fn to_token_iter( &self, ) -> ShadowCountedIter<'_, <TokenStream as IntoIterator>::IntoIter>

Convert &self into a TokenIter object.

fn into_token_iter<'a>( self, ) -> ShadowCountedIter<'a, <TokenStream as IntoIterator>::IntoIter>

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.
