Struct LeftPadder

Source 
pub struct LeftPadder<'a> { /* private fields */ }
Available on crate feature slices only.
Expand description

Add padding to a string in its Display impl.

§Example

use core_extensions::strings::LeftPadder;
 
assert_eq!(LeftPadder::new("foo\n bar", 0).to_string(), "foo\n bar");
assert_eq!(LeftPadder::new("foo\n bar", 1).to_string(), " foo\n  bar");
assert_eq!(LeftPadder::new("foo\n bar", 2).to_string(), "  foo\n   bar");
assert_eq!(LeftPadder::new("foo\n bar", 4).to_string(), "    foo\n     bar");
