Struct lamcal::CharPosition

pub struct CharPosition { /* fields omitted */ }

Represents a position in a stream of chars.

The first character in a stream is at line 1 and column 1. Every newline character advances the line by 1 and resets the column so that the next character gets column 1 at the next line.

Methods

impl CharPosition

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

Constructs a new CharPosition with given line and column number.

pub fn with_newline(line: usize, column: usize, newline: bool) -> Self

Constructs a new CharPosition with given line and column number and an indicator, that the next character is positioned at a new line.

pub fn line(&self) -> usize

Returns the line number of this position.

pub fn column(&self) -> usize

Returns the column number of this position.

pub fn newline(&self) -> bool

Returns the newline indicator of this position.

pub fn next(&mut self, chr: char)

Advances this position to the next character.

The first character in a stream is at line 1 and column 1. Every newline character advances the line by 1 and resets the column so that the next character gets column 1 at the next line.
