[][src]Trait std::slice::SliceConcatExt

pub trait SliceConcatExt<T> where

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
1.0.0

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]);Run

fn join(&self, sep: &T) -> Self::Output
1.3.0

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]);Run

fn connect(&self, sep: &T) -> Self::Output
1.0.0

Deprecated since 1.3.0:

renamed to join
