Returns true if the verification has been cancelled, either by us or the other side.
The ID of the other user in the verification process.
Alias for on.
Cancel a verification.
We will send an m.key.verification.cancel if the verification is still in flight. The verification promise
will reject, and a VerifierEvent.Cancel will be emitted.

true if the event had listeners, false otherwise.
Rest...args: Parameters<VerifierEventHandlerMap[T]>Get the details for reciprocating QR code verification, if one is in progress
Returns null, unless this verifier is for reciprocating a QR-code-based verification (ie, the other user has
already scanned our QR code), and we are waiting for the user to confirm.
Get the details for an SAS verification, if one is in progress
Returns null, unless this verifier is for a SAS-based verification and we are waiting for the user to confirm
the SAS matches.
Returns the number of listeners listening to the event named event.
The name of the event being listened for
Returns a copy of the array of listeners for the event named event.
Alias for removeListener
Adds the listener function to the end of the listeners array for the
event named event.
No checks are made to see if the listener has already been added. Multiple calls
passing the same combination of event and listener will result in the listener
being added, and called, multiple times.
By default, event listeners are invoked in the order they are added. The prependListener method can be used as an alternative to add the event listener to the beginning of the listeners array.
The name of the event.
The callback function
a reference to the EventEmitter, so that calls can be chained.
Adds a one-time listener function for the event named event. The
next time event is triggered, this listener is removed and then invoked.
Returns a reference to the EventEmitter, so that calls can be chained.
By default, event listeners are invoked in the order they are added. The prependOnceListener method can be used as an alternative to add the event listener to the beginning of the listeners array.

Returns a copy of the array of listeners for the event named eventName,
including any wrappers (such as those created by .once()).
Removes all listeners, or those of the specified event.
It is bad practice to remove listeners added elsewhere in the code,
particularly when the EventEmitter instance was created by some other
component or module (e.g. sockets or file streams).
Optionalevent: EventEmitterEvents | VerifierEventThe name of the event. If undefined, all listeners everywhere are removed.

Removes the specified listener from the listener array for the event named event.

Start the key verification, if it has not already been started.
This means sending a m.key.verification.start if we are the first responder, or a m.key.verification.accept
if the other side has already sent a start event.
Promise which resolves when the verification has completed, or rejects if the verification is cancelled or times out.
A
Verifieris responsible for performing the verification using a particular method, such as via QR code or SAS (emojis).A verifier object can be created by calling
VerificationRequest.beginVerification; one is also created automatically when am.key.verification.startevent is received for an existing VerificationRequest.Once a verifier object is created, the verification can be started by calling the Verifier#verify method.
