Number literal defaults to i32, failing to satisfy the ToUsize trait

[ChaoticWyrme]

When you use a literal as the argument to take, it assumes it is an i32 by default, and has a compilation error, since i32s cannot be turned into usize. The workaround is to create a variable with an explicit u* type, and pass it in.

Prerequisites

• Rust version : rustc 1.70.0 (90c541806 2023-05-31)
• nom version : 7.1.3
• nom compilation features used: std

Test case

use nom::bytes::complete::take;

fn main() {
    let data = [1, 2, 3, 4, 5];
    println!("{:?}", take(1)(data.as_slice()).unwrap());
}

On the rust playground

A slightly less awkward workaround is to specify the type of the literal directly (i.e. 1_usize), but that's obviously still not ideal.
