Provides a means for integration of async PHP platforms ([related docs](data-fetching.md#async-php)).
Table of Contents
- all() : Promise
- Given an iterable of promises (or values), returns a promise that is fulfilled when all the items in the iterable are fulfilled.
- convertThenable() : Promise
- Converts thenable of the underlying platform into Automattic\WooCommerce\Vendor\GraphQL\Executor\Promise\Promise instance.
- create() : Promise
- Creates a Promise from the given resolver callable.
- createFulfilled() : Promise
- Creates a fulfilled Promise for a value if the value is not a promise.
- createRejected() : Promise
- Creates a rejected promise for a reason if the reason is not a promise.
- isThenable() : bool
- Is the value a promise or a deferred of the underlying platform?
- then() : Promise
- Accepts our Promise wrapper, extracts adopted promise out of it and executes actual `then` logic described in Promises/A+ specs. Then returns new wrapped instance of Automattic\WooCommerce\Vendor\GraphQL\Executor\Promise\Promise.
Methods

Parameters
- $thenable : mixed
Return values
Promise —create()
Creates a Promise from the given resolver callable.
public
create(callable $resolver) : Promise
Parameters
- $resolver : callable
Return values
Promise —createFulfilled()
Creates a fulfilled Promise for a value if the value is not a promise.
public
createFulfilled([mixed $value = null ]) : Promise
Parameters
- $value : mixed = null
Return values
Promise —createRejected()
Creates a rejected promise for a reason if the reason is not a promise.
public
