Struct regex_syntax::ast::Position

[+] Show declaration

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

[−] Expand description

A single position in a regular expression.

A position encodes one half of a span, and include the byte offset, line number and column number.

Fields

offset: usize

[−] Expand description

The absolute offset of this position, starting at 0 from the beginning of the regular expression pattern string.

line: usize

[−] Expand description

The line number, starting at 1.

column: usize

[−] Expand description

The approximate column number, starting at 1.

Methods

impl Position[−]

pub fn new(offset: usize, line: usize, column: usize) -> Position[−]

Create a new position with the given information.

offset is the absolute offset of the position, starting at 0 from the beginning of the regular expression pattern string.

line is the line number, starting at 1.

column is the approximate column number, starting at 1.
