Struct Position 

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

A position in source code.

Represents a single point in the source file with line, column, and byte offset.

Fields

line: usize

Line number (1-indexed)

column: usize

Column number (1-indexed)

offset: usize

Byte offset in source (0-indexed)

Implementations

impl Position

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

Create a new position.

Arguments

• line - Line number (1-indexed)
• column - Column number (1-indexed)
• offset - Byte offset (0-indexed)

pub fn start() -> Self

Create a position at the start of the 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 Display for Position

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

Formats the value using the given formatter.

impl Hash for Position

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

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.
