HH\Pair::concat

Returns an ImmVector that is the concatenation of the values of the current Pair and the values of the provided Traversable

public function concat<Tu super mixed>(
  Traversable<mixed, Tu> $traversable,
): ImmVector<mixed, Tu>;

The values of the provided Traversable is concatenated to the end of the current Pair to produce the returned ImmVector.

Guide

• Constraints

Parameters

• Traversable<mixed,Tu> $traversable - The Traversable to concatenate to the current Pair.

Returns

• ImmVector<mixed,Tu> - The concatenated ImmVector.

Examples

This example creates a new ImmVector by concatenating a Traversable with the values in the Pair.

$p = Pair {'foo', -1.5};

$v = $p->concat(vec[100, 'bar']);
\var_dump($v);
