Struct scribe::buffer::Range

pub struct Range { /* fields omitted */ }

A two-position type, representing a span of characters.

Methods

impl Range

fn new(start: Position, end: Position) -> Range

Creates a new buffer range. Checks and swaps arguments in the event that the end precedes the start.

fn start(&self) -> Position

fn end(&self) -> Position

fn includes(&self, position: &Position) -> bool

Whether or not the range includes the specified position. The range is exclusive, such that its ending position is not included.

Examples

use scribe::buffer::{Position, Range};

// Builder a range.
let range = Range::new(
    Position{ line: 0, offset: 0 },
    Position{ line: 1, offset: 5 }
);

assert!(range.includes(
    &Position{ line: 1, offset: 0 }
));

assert!(range.includes(
    &Position{ line: 1, offset: 4 }
));

assert!(!range.includes(
    &Position{ line: 1, offset: 5 }
));
