Struct LineIndexer 

pub struct LineIndexer(/* private fields */);

An Indexer that stores ending positions of every line (including trailing newlines).

Implementations

impl LineIndexer

pub fn new(s: &str) -> Box<Self>

Create an LineIndexer.

Trait Implementations

impl Debug for LineIndexer

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

Formats the value using the given formatter.

impl Indexer for LineIndexer

fn line_col_at(&self, pos: usize) -> (usize, usize)

Returns the line and column number of this Position.

fn line_span_at(&self, pos: usize) -> (usize, usize)

Returns the start and the end of the line that contains the position at pos.

fn span_with_context_lines( &self, start: usize, end: usize, context_lines_before: usize, context_lines_after: usize, ) -> (usize, usize)

Returns the start and the end of the (context_lines_before + 1 + context_lines_after) lines that contains the position at pos.

impl PartialEq for LineIndexer

fn eq(&self, other: &LineIndexer) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
