proxiableUUID

function proxiableUUID() external view virtual returns (bytes32)

_Implementation of the ERC1822 {proxiableUUID} function. This returns the storage slot used by the implementation. It is used to validate the implementation's compatibility when performing an upgrade.

IMPORTANT: A proxy pointing at a proxiable contract should not be considered proxiable itself, because this risks bricking a proxy that upgrades to it, by delegating to itself until out of gas. Thus it is critical that this function revert if invoked through a proxy. This is guaranteed by the notDelegated modifier._

upgradeTo

function upgradeTo(address newImplementation) public virtual

_Upgrade the implementation of the proxy to newImplementation.

Calls {_authorizeUpgrade}.

Emits an {Upgraded} event._

upgradeToAndCall

function upgradeToAndCall(address newImplementation, bytes data) public payable virtual

_Upgrade the implementation of the proxy to newImplementation, and subsequently execute the function call encoded in data.

Calls {_authorizeUpgrade}.

Emits an {Upgraded} event._

Upgraded

event Upgraded(address implementation)

Emitted when the implementation is upgraded.

AdminChanged

event AdminChanged(address previousAdmin, address newAdmin)

Emitted when the admin account has changed.

BeaconUpgraded

event BeaconUpgraded(address beacon)

Emitted when the beacon is changed.
