[Rust Bug] IO输入字符串和String__new()不相等?
rust
use std::io;
fn main() {
let mut s1 = String::new();
let mut s2 = String::from("ss123");
io::stdin()
.read_line(&mut s1)
.expect("Failed to read line");
println!("{}", s1 == s2);
println!("{}", s1.trim() == s2);
// Input ss123
// Output false
// Output true
}
为什么呢??? 因为多了 \r 和 \n
输入前
输入值后
