btoi

Parse integers from ASCII byte slices.

Introduction

Provides functions similar to from_str_radix, but is faster when parsing directly from byte slices instead of strings.

Supports #![no_std].

use btoi::btoi;

assert_eq!(Ok(42), btoi(b"42"));
assert_eq!(Ok(-1000), btoi(b"-1000"));

MSRV policy

The minimum supported Rust version is 1.60, matching num_traits, with no intent to ever increase it.

That's because #![feature(int_from_ascii)] in the standard library will hopefully eventually make this crate obsolete for new versions of Rust, and so old versions are the priority.

Changelog
