Struct Position 

pub struct Position {
    pub line: usize,
    pub column: usize,
    pub offset: usize,
}

Represents a position in source code with line, column, and absolute offset.

Positions use 1-based indexing for line and column numbers to match conventional text editor behavior.

Fields

line: usize

Line number (1-based)

column: usize

Column number (1-based)

offset: usize

Absolute character offset from the beginning of the source (0-based)

Implementations

impl Position

pub fn new(line: usize, column: usize, offset: usize) -> Self

Creates a new position with the given line, column, and offset.

pub fn start() -> Self

Creates a position representing the start of a source file.

Trait Implementations

impl Clone for Position

fn clone(&self) -> Position

Returns a duplicate of the value.

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 Default for Position

fn default() -> Self

Returns the “default value” for a type.

impl Display 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.

impl Copy for Position
