use rustils::parse::byte::ToI8;
use rustils::error::ParseError::InvalidNumber;
let a = -128_i32;
let b = 127_i32;
let c = -129_i32;
let d = 128_i32;
//Rust
assert_eq!(a as i8, -128_i8);
assert_eq!(b as i8, 127_i8);
assert_eq!(c as i8, 127_i8);
assert_eq!(d as i8, -128_i8);
//rustils
assert_eq!(a.to_i8(), -128_i8);
assert_eq!(b.to_i8(), 127_i8);
assert_eq!(c.to_i8_res(), Err(InvalidNumber("-129".to_string())));
assert_eq!(d.to_i8_res(), Err(InvalidNumber("128".to_string())));use rustils::string::StringUtils;
let text = "你好。How are you?";
//Rust function
assert_eq!(text.find('好'), Some(3));
//rustils functions
assert_eq!(text.find_char_opt('好'), Some(1));
assert_eq!(text.find_char('好'), 1);use rustils::string::StringUtils;
let text1 = &mut String::from("你好。How are you?");
//Rust function
assert_eq!(text1.remove(3), '好');
assert_eq!(text1, "你。How are you?");
let text3 = String::from("你好。How are you?");
let text4 = &mut String::from("你好。How are you?");
