Trait std::slice::SliceConcatExt

pub trait SliceConcatExt<T> where
    T: ?Sized, {
    type Output;
    fn concat(&self) -> Self::Output;
    fn join(&self, sep: &T) -> Self::Output;
    fn connect(&self, sep: &T) -> Self::Output;
}

trait should not have to exist

An extension trait for concatenating slices

While this trait is unstable, the methods are stable. SliceConcatExt is included in the standard library prelude, so you can use join() and concat() as if they existed on [T] itself.

Required methods

fn concat(&self) -> Self::Output

Flattens a slice of T into a single value Self::Output.

Examples

assert_eq!(["hello", "world"].concat(), "helloworld");
assert_eq!([[1, 2], [3, 4]].concat(), [1, 2, 3, 4]);

fn join(&self, sep: &T) -> Self::Output

Flattens a slice of T into a single value Self::Output, placing a given separator between each.

Examples

assert_eq!(["hello", "world"].join(" "), "hello world");
assert_eq!([[1, 2], [3, 4]].join(&0), [1, 2, 0, 3, 4]);

fn connect(&self, sep: &T) -> Self::Output

Deprecated since 1.3.0:

renamed to join

Flattens a slice of T into a single value Self::Output, placing a given separator between each.

Examples

assert_eq!(["hello", "world"].connect(" "), "hello world");
assert_eq!([[1, 2], [3, 4]].connect(&0), [1, 2, 0, 3, 4]);
