Struct Preprocessor 

pub struct Preprocessor { /* private fields */ }

A stateful preprocessor, intended to be run on sequential lines of the same file.

The state tracks multi-line comments/strings best-effort. If the diff begins inside an existing comment/string, the preprocessor cannot infer that.

Implementations

impl Preprocessor

pub fn new(opts: PreprocessOptions) -> Self

pub fn with_language(opts: PreprocessOptions, lang: Language) -> Self

Create a new preprocessor with language-specific syntax support.

pub fn set_language(&mut self, lang: Language)

Set the language for this preprocessor and reset state.

pub fn reset(&mut self)

pub fn sanitize_line(&mut self, line: &str) -> String

Returns a sanitized line where masked segments are replaced with spaces.

The output is the same length in bytes as the input.
