Struct rustc_parse::parser::TokenCursor

struct TokenCursor {
    tree_cursor: TokenTreeCursor,
    stack: Vec<(TokenTreeCursor, Delimiter, DelimSpan)>,
}

Iterator over a TokenStream that produces Tokens. It’s a bit odd that we (a) lex tokens into a nice tree structure (TokenStream), and then (b) use this type to emit them as a linear sequence. But a linear sequence is what the parser expects, for the most part.

Fields

tree_cursor: TokenTreeCursor

stack: Vec<(TokenTreeCursor, Delimiter, DelimSpan)>

Implementations

impl TokenCursor

fn next(&mut self) -> (Token, Spacing)

fn inlined_next(&mut self) -> (Token, Spacing)

This always-inlined version should only be used on hot code paths.

Trait Implementations

impl Clone for TokenCursor

fn clone(&self) -> TokenCursor

Returns a copy of the value.

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

Performs copy-assignment from source.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
