Trait write_fonts::util::WrappingGet

pub trait WrappingGet<T> {
    // Required methods
    fn wrapping_next(&self, idx: usize) -> &T;
    fn wrapping_prev(&self, idx: usize) -> &T;
}

Read next or previous, wrapping if we go out of bounds.

This is particularly useful when porting from Python where reading idx - 1, with -1 meaning last, is common.

Required Methods

fn wrapping_next(&self, idx: usize) -> &T

fn wrapping_prev(&self, idx: usize) -> &T
