Struct LineIndex 

pub struct LineIndex<'a> { /* private fields */ }

Implementations

impl<'a> LineIndex<'a>

pub fn new(content: &'a str) -> Self

pub fn with_line_starts(content: &'a str, line_starts: Vec<usize>) -> Self

Create a LineIndex from pre-computed line start byte offsets. Each entry is the byte offset of the first character on that line. The first entry must be 0 (start of content).

pub fn with_line_starts_and_code_blocks( content: &'a str, line_starts: Vec<usize>, code_block_byte_ranges: &[(usize, usize)], ) -> Self

Create a LineIndex from pre-computed line starts and code block byte ranges.

Instead of re-scanning content to find code blocks, this converts the already-detected byte ranges into line-level information.

pub fn line_col_to_byte_range(&self, line: usize, column: usize) -> Range<usize>

pub fn line_col_to_byte_range_with_length( &self, line: usize, column: usize, length: usize, ) -> Range<usize>

Calculate a proper byte range for replacing text with a specific length This is the correct function to use for LSP fixes

Safety

This function correctly handles multi-byte UTF-8 characters by converting character positions (columns) to byte positions.

pub fn whole_line_range(&self, line: usize) -> Range<usize>

Calculate byte range for entire line replacement (including newline) This is ideal for rules that need to replace complete lines

pub fn multi_line_range( &self, start_line: usize, end_line: usize, ) -> Range<usize>

Calculate byte range spanning multiple lines (from start_line to end_line inclusive) Both lines are 1-indexed. This is useful for replacing entire blocks like tables.

pub fn line_text_range( &self, line: usize, start_col: usize, end_col: usize, ) -> Range<usize>

Calculate byte range for text within a line (excluding newline) Useful for replacing specific parts of a line

Safety

This function correctly handles multi-byte UTF-8 characters by converting character positions (columns) to byte positions.

pub fn line_content_range(&self, line: usize) -> Range<usize>

Calculate byte range from start of line to end of line content (excluding newline) Useful for replacing line content while preserving line structure

pub fn get_line_start_byte(&self, line_num: usize) -> Option<usize>

Get the global start byte offset for a given 1-based line number.

pub fn is_code_block(&self, line: usize) -> bool

Check if the line at the given index is within a code block

pub fn is_code_fence(&self, line: usize) -> bool

Check if the line is a code fence marker (``` or ~~~)

pub fn is_tilde_code_block(&self, line: usize) -> bool

Check if the line is a tilde code fence marker (~~~)

pub fn get_content(&self) -> &str

Get a reference to the content

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
