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;
}
🔬 This is a nightly-only experimental API. (slice_concat_ext #27747)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.

Associated Types

The resulting type after concatenation

Required Methods

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]);

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]);

Deprecated since 1.3.0: renamed to join
