str Utils

This crate provides some traits to extend [u8], str and Cow<str>.

Examples

use str_utils::*;

assert_eq!(true, "foobar".starts_with_ignore_ascii_case("FoO"));
assert_eq!(Some(1), "photo.jpg".ends_with_ignore_ascii_case_multiple(&[".png", ".jpg", ".gif"]));
assert_eq!(true, "http".eq_ignore_ascii_case_with_uppercase("HTTP")); // faster than `eq_ignore_ascii_case`
assert_eq!(true, "foobar".starts_with_ignore_ascii_case("FoO"));

assert_eq!("here is a ZERO_WIDTH_SPACE -> ​".len() - 3, "here is a ZERO_WIDTH_SPACE -> ​".remove_all_invisible_characters().len());

assert_eq!(r"foo\% b\_r", r"foo% b_r".escape_ascii_characters(b'\\', b"%_"));

assert!(!"AaBb\u{0130}Zz".is_lowercased());
assert!(!"AaBbZz".is_ascii_lowercased());
assert!(!"aabbßzz".is_uppercased());
assert!(!"aabbzz".is_ascii_uppercased());

assert_eq!("aabbi\u{0307}zz", "AaBb\u{0130}Zz".to_lowercase_cow());
assert_eq!("aabb\u{0130}zz", "AaBb\u{0130}Zz".to_ascii_lowercase_cow());
assert_eq!("AABBSSZZ", "aabbßzz".to_uppercase_cow());
assert_eq!("AABBßZZ", "aabbßzz".to_ascii_uppercase_cow());

assert_eq!("Line 1 Line 2 Line 2 Line 3 Line 4 Line 5", "Line 1\r\nLine 2\r\nLine 2\rLine 3\nLine 4\nLine 5".replace_newlines_with_space());

assert_eq!("abc", Cow::from(" abc ").trim_cow()); // the `trim_cow` family of methods can be used on a `Cow<str>` to allow fluent method chaining.
