Stop Beam

Once a beam is created, it can be stopped by the sender who is the one who deposits the tokens for streaming to the recipient.

public shared ({ caller }) func stopBeam(escrowId : EscrowId) : async Result<BeamStatus, ErrorCode>

Restart Beam

Similarly, when a beam is stopped, it can only be restarted by the sender.

public shared ({ caller }) func restartBeam(escrowId : EscrowId) : async Result<BeamStatus, ErrorCode>
