Struct const_format::Sliced

pub struct Sliced<T, R>(pub T, pub R);

Available on crate feature fmt only.

Expand description

Wrapper for writing a range of a string slice.

This is a workaround for not being able to do &string[start..end] at compile-time.

Example

#![feature(const_mut_refs)]

use const_format::Sliced;
use const_format::{concatc, formatc};

const NUMS: &str = "0123456789";
const SRC: &str = "foo bar baz";

assert_eq!(concatc!(Sliced(NUMS, 1..=4)), "1234");
assert_eq!(concatc!(Sliced(SRC, 0..5), "ros."), "foo bros.");

assert_eq!(formatc!("{}", Sliced(NUMS, 4..)), "456789");
assert_eq!(formatc!("{}t", Sliced(SRC, 4..7)), "bart");
