Implementations

impl TextLines

pub fn new(text: &str) -> TextLines

Creates a new TextLines with the specified text and default indent width of 4.

pub fn with_indent_width(text: &str, indent_width: usize) -> TextLines

Creates a new TextLines with the specified text and indent width. The indent width sets the width of a tab character when getting the display column.

pub fn lines_count(&self) -> usize

Gets the number of lines in the text.

pub fn text_length(&self) -> usize

Gets the text length in bytes.

pub fn line_index(&self, byte_index: usize) -> usize

Gets the line index from a byte index. Note that if you provide the middle byte index of a \r\n newline then it will return the index of the line the preceding line.

pub fn line_start(&self, line_index: usize) -> usize

Gets the line start byte index.

pub fn line_end(&self, line_index: usize) -> usize

Gets the line end byte index (before/at the newline character).

pub fn line_range(&self, line_index: usize) -> (usize, usize)

Gets the line range.

pub fn byte_index(&self, line_and_column: LineAndColumnIndex) -> usize

Gets the byte position from the provided line and column index.

pub fn line_and_column_index(&self, byte_index: usize) -> LineAndColumnIndex

Gets the line and column index of the provided byte index.

pub fn line_and_column_display(&self, byte_index: usize) -> LineAndColumnDisplay

Gets the line and column display based on the indentation width and the provided byte index.

pub fn line_and_column_display_with_indent_width(
    &self,
    byte_index: usize,
    indent_width: usize
) -> LineAndColumnDisplay

Gets the line and column display based on the provided byte index and indentation width.
