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

    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;
    }

Unstable (`slice_concat_ext` #27747)

: trait should not have to exist

An extension trait for concatenating slices

## Associated Types

### `type Output`

Unstable (`slice_concat_ext` #27747)

: trait should not have to exist

The resulting type after concatenation

## 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");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");Run

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

Deprecated since 1.3.0

: renamed to join

## Implementors

- `impl<T, V> SliceConcatExt<T> for [V] where T: Clone, V: Borrow<[T]>`
- `impl<S> SliceConcatExt<str> for [S] where S: Borrow<str>`

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)
