Utility functions for Display/Debug trait comparison in no_std environment.

This crate provides functions to compare output of Display and Debug traits against &str in no_std env. No alloc nor std is used.

Quick Start

```rust

![no_std]

use fmtcomparenostd::eq_display; use core::fmt::{Display, Formatter, Result};

struct D {}

impl Display for D { fn fmt(&self, f: &mut Formatter<'_>) -> Result { write!(f, "Display D") } }

fn main() { assert!(eq_display(&D {}, "Display D")); } ```
