A tiny Rust crate that implements parts of the WHATWG Infra Standard. Specifically, it implements the following:

• 4.5. Code points
• 4.6. Strings

It exposes a small set of primitives that are useful for parsing text into machine-readable data.

cargo add whatwg-infra

You can import individual functions:

use whatwg_infra::{
	is_ascii_tab_newline,
	is_c0_control,
	is_c0_control_space,
	is_noncharacter
};

assert!(is_ascii_tab_newline('\t'));
assert!(is_c0_control('\u{0000}'));
assert!(is_c0_control_space('\u{0020}'));

You can also import the traits to get all the functionality, and execute the methods on the types directly.

use whatwg_infra::{InfraScalarValue, InfraStr, InfraUtf16Surrogate};

assert_eq!('a'.is_ascii_tab_newline(), false);
assert_eq!('\u{001E}'.is_c0_control(), true);
assert_eq!('\n'.is_c0_control_space(), true);
assert_eq!('\u{CFFFF}'.is_noncharacter(), true);

This crate does not depend on libstd, and can be used in #![no_std] environments.
