Struct rustdoc::html::highlight::Classifier

struct Classifier<'a> {
    tokens: Peekable<TokenIter<'a>>,
    in_attribute: bool,
    in_macro: bool,
    in_macro_nonterminal: bool,
    edition: Edition,
    byte_pos: u32,
    src: &'a str,
}

Processes program tokens, classifying strings of text by highlighting category (Class).

Fields

tokens: Peekable<TokenIter<'a>>

in_attribute: bool

in_macro: bool

in_macro_nonterminal: bool

edition: Edition

byte_pos: u32

src: &'a str

Implementations

impl<'a> Classifier<'a>

fn new(src: &str, edition: Edition) -> Classifier<'_>

fn get_full_ident_path(&mut self) -> Vec<(TokenKind, usize, usize)>

Concatenate colons and idents as one when possible.

fn next(&mut self) -> Option<(TokenKind, &'a str)>

Wraps the tokens iteration to ensure that the byte_pos is always correct.

fn highlight(self, sink: &mut dyn FnMut(Highlight<'a>))

Exhausts the Classifier writing the output into sink.

The general structure for this method is to iterate over each token, possibly giving it an HTML span with a class specifying what flavor of token is used.

fn advance(
    &mut self,
    token: TokenKind,
    text: &'a str,
    sink: &mut dyn FnMut(Highlight<'a>)
)

Single step of highlighting. This will classify token, but maybe also a couple of following ones as well.

fn peek(&mut self) -> Option<TokenKind>

Layout

Note: Most layout information is completely unstable and may be different between compiler versions and platforms. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
