Struct castle_input_cursor::Position

pub struct Position {
    pub line_number: NonZeroU32,
    pub column_number: NonZeroU32,
}

A position in the source code.

Stores both the column number and the line number.

Note that spans are of the form [begining, end) i.e. that the begining position is inclusive and the end position is exclusive. See test check_positions from syntax/lexer/tests.rs for an example.

Fields

line_number: NonZeroU32

Line number.

column_number: NonZeroU32

Column number.

Implementations

impl Position

pub fn new(line_number: u32, column_number: u32) -> Self

Creates a new Position.

pub fn line_number(self) -> u32

Gets the line number of the position.

pub fn column_number(self) -> u32

Gets the column number of the position.
