示例

match_indices

fn main() {
    let name = "\nJiang\nBo\n";
    name.match_indices(char::is_alphabetic)
        .for_each(|e| println!("{e:?}"));
}

rmatch_indices

fn main() {
    let name = "\nJiang\nBo\n";
    name.rmatch_indices(char::is_alphabetic)
        .for_each(|e| println!("{e:?}"));
}

trim

fn main() {
    let name = "\nJiang\nBo\n";
    println!("{:?}", name.trim());
}

trim_start

fn main() {
    let name = "\nJiang\nBo\n";
    println!("{:?}", name.trim_start());
}

trim_end

fn main() {
    let name = "\nJiang\nBo\n";
    println!("{:?}", name.trim_end());
}

trim_matches

fn main() {
    let name = "\nJiang\nBo\n";
    println!("{:?}", name.trim_matches('\n'));
}

trim_start_matches

fn main() {
    let name = "\nJiang\nBo\n";
    println!("{:?}", name.trim_start_matches('\n'));
}

trim_end_matches

fn main() {
    let name = "\nJiang\nBo\n";
    println!("{:?}", name.trim_end_matches('\n'));
}

strip_prefix

fn main() {
    let name = "\nJiang\nBo\n";
    println!("{:?}", name.strip_prefix('\n'));
}
