Struct WhereClause 

pub struct WhereClause {
    pub _pred: VerbatimUntil<Colon>,
    pub _colon: Colon,
    pub bounds: VerbatimUntil<Either<Comma, Semicolon, BraceGroup>>,
}

Represents a single predicate within a where clause.

Fields

_pred: VerbatimUntil<Colon>

The type or lifetime being constrained (e.g., T or 'a).

_colon: Colon

The colon separating the constrained item and its bounds.

bounds: VerbatimUntil<Either<Comma, Semicolon, BraceGroup>>

The bounds applied to the type or lifetime (e.g., Trait or 'b).

Trait Implementations

impl Clone for WhereClause

fn clone(&self) -> WhereClause

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WhereClause

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

Formats the value using the given formatter.

impl Parser for WhereClause

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 WhereClause

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.

impl ToTokens for WhereClause

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

Write self to the given TokenStream.

fn to_token_stream(&self) -> TokenStream

Convert self directly into a TokenStream object.

fn into_token_stream(self) -> TokenStream

where Self: Sized,

Convert self directly into a TokenStream object.
