Struct Position

pub struct Position { /* private fields */ }

Represents a position in the source code. The line and column are zero-based, character offsets. It is different from tree-sitter’s position which is zero-based byte offsets. Note, accessing column is O(n) operation.

Implementations

impl Position

pub fn new(line: usize, byte_column: usize, byte_offset: usize) -> Self

pub fn line(&self) -> usize

pub fn column<D: Doc>(&self, node: &Node<'_, D>) -> usize

Returns the column in terms of characters. Note: node does not have to be a node of matching position.

pub fn byte_point(&self) -> (usize, usize)

Trait Implementations

impl Clone for Position

fn clone(&self) -> Position

Returns a duplicate of the value.

const fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Position

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

Formats the value using the given formatter.

impl PartialEq for Position

fn eq(&self, other: &Position) -> 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.
