[−][src]Struct rustdoc::html::highlight::Classifier
Processes a program (nested in the internal lexer
), classifying strings of
text by highlighting category (Class
). Calls out to a Writer
to write
each span of text in sequence.
Fields
lexer: StringReader<'a>
source_map: &'a SourceMap
in_attribute: bool
in_macro: bool
in_macro_nonterminal: bool
Methods

impl<'a> Classifier<'a>
fn new(lexer: StringReader<'a>, source_map: &'a SourceMap) -> Classifier<'a>
[src]
fn new(lexer: StringReader<'a>, source_map: &'a SourceMap) -> Classifier<'a>
fn try_next_token(&mut self) -> Result<TokenAndSpan>
[src]
fn try_next_token(&mut self) -> Result<TokenAndSpan>
Gets the next token out of the lexer, emitting fatal errors if lexing fails.
fn write_source<W: Writer>(&mut self, out: &mut W) -> Result<()>
[src]
fn write_source<W: Writer>(&mut self, out: &mut W) -> Result<()>
Exhausts the lexer
writing the output into out
.
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. All source code emission is done as slices from the source map, not from the tokens themselves, in order to stay true to the original source.

&mut self,

Create an error for a missing method specialization. Defaults to panicking with type, trait & method names. S
is the encoder/decoder state type, T
is the type being encoded/decoded, and the arguments are the names of the trait and method that should've been overridden. Read more
