Struct Pos 

pub struct Pos {
    pub byte_offset: usize,
    pub char_offset: usize,
    pub line: usize,
    pub column: usize,
}

A position within the input stream.

line is 1-based; column is 0-based.

Fields

byte_offset: usize

char_offset: usize

line: usize

column: usize

Implementations

impl Pos

pub const ORIGIN: Self

The position representing the start of a document.

pub const fn advance(self, ch: char) -> Self

Advance the position by one character.

If ch is a line feed (\n) the line counter is incremented and the column is reset to 0. For all other characters the column advances by one. byte_offset advances by ch.len_utf8() and char_offset always advances by 1.

Trait Implementations

impl Clone for Pos

fn clone(&self) -> Pos

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Pos

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

Formats the value using the given formatter.

impl PartialEq for Pos

fn eq(&self, other: &Pos) -> 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 Pos

impl Eq for Pos

impl StructuralPartialEq for Pos
