Trait PositionExt

pub trait PositionExt {
    const MAX: Self;
    const MIN: Self;

    // Required methods
    fn offset(&mut self, lines: i32, characters: i32);
    fn set_line(&mut self, line: u32);
    fn set_character(&mut self, character: u32);
    fn is_in_bounds(&self, start: Self, end: Self) -> bool;
    fn is_after(&self, position: Self) -> bool;
    fn is_before(&self, position: Self) -> bool;
}

Extands the Position type by adding helper functions.

Required Associated Constants

const MAX: Self

The largest value that can be represented by a Position.

const MIN: Self

The smallest value that can be represented by a Position.

Required Methods

fn offset(&mut self, lines: i32, characters: i32)

Offsets the current position by lines and characters. If you’re adding both lines and characters, making sure to set characters to 0 before calling this function to ensure correct results.

fn set_line(&mut self, line: u32)

Sets line to a specific value.

fn set_character(&mut self, character: u32)

Sets character to a specific value.

fn is_in_bounds(&self, start: Self, end: Self) -> bool

Checks whether or not this position is between the 2 passed positions.

fn is_after(&self, position: Self) -> bool

Checks whether or not this position is after the passed position.

fn is_before(&self, position: Self) -> bool

Checks whether or not this position is before the passed position.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
