| 描述 | grass is a pure-Rust Sass-to-CSS compiler. When the parser encounters a syntax error, it constructs a diagnostic via `grass_compiler::raw_to_parse_error`, which hands the byte-offset error span to the `codemap` crate for line/column resolution. If the error span boundary falls inside a multi-byte UTF-8 character, `codemap::File::find_line_col` attempts `&source[start..end]` on a non-char-boundary index and Rust panics with `"byte index N is not a char boundary; it is inside ..."`. The panic propagates up through the public `grass::from_string` API and aborts the process.
This violates the documented contract that `grass::from_string` returns `Result<String, Box<grass::Error>>` for all inputs, but a malformed SCSS source should yield `Err`, not crash the process. |
