Rut
Rut is a small UTF-8 parsing library for applications that need to parse individual chars.
It provides a byte-wise parsing mechanism, and functions for processing byte slices.
It is completely #[no_std] and should produce very small binaries.[citation needed]
Conformance
Rut aims to be fully conformant to the specifications and restrictions of the Unicode standard.
Due to the nature of byte-wise parsing, some extra caution might be required when using Rut.
The parse_one and parse functions take care of this.
Testing
A few tests validating the expected behavior are already in place, but it is not comprehensive by any means yet. More tests will be added.
Examples
use rut::Utf8Parser; // UTF-8 encoding of '€' let bytes = [0xE2, 0x82, 0xAC]; let mut p = Utf8Parser::new(); assert_eq!(p.parse_byte(bytes[0]), Ok(None)); assert_eq!(p.parse_byte(bytes[1]), Ok(None)); assert_eq!(p.parse_byte(bytes[2]), Ok(Some('€')));
