Struct spinoso_string::Center[][src]

pub struct Center<'a, 'b> { /* fields omitted */ }

An iterator that yields a byte string centered within a padding byte string.

This struct is created by the center method on a Spinoso String. See its documentation for more.

Examples

use spinoso_string::String;

let s = String::from("hello");

assert_eq!(s.center(4, None).collect::<Vec<_>>(), b"hello");
assert_eq!(s.center(20, None).collect::<Vec<_>>(), b"       hello        ");
assert_eq!(s.center(20, Some(&b"123"[..])).collect::<Vec<_>>(), b"1231231hello12312312");

This iterator is encoding-aware. Conventionally UTF-8 strings are iterated by UTF-8 byte sequences.

use spinoso_string::String;

let s = String::from("💎");

assert_eq!(s.center(3, None).collect::<Vec<_>>(), " 💎 ".as_bytes());
