_ADMIN_SLOT
Storage slot with the admin of the contract. This is the keccak-256 hash of "eip1967.proxy.admin" subtracted by 1, and is validated in the constructor.

Storage slot with the address of the current dummy-implementation. This is the keccak-256 hash of "eip1967.proxy.implementation" subtracted by 1, and is validated in the constructor.

_getSlotImplSigsSlot
Returns the storage slot which stores the sigs array set for the implementation.
function _getSlotImplSigsSlot(address implementation_) internal pure returns (bytes32);_getSlotSigsImplSlot
Returns the storage slot which stores the implementation address for the function sig.
function _getSlotSigsImplSlot(bytes4 sig_) internal pure returns (bytes32 result_);_getAddressSlot
Returns an address data_ located at slot_.
function _getAddressSlot(bytes32 slot_) internal view returns (address data_);_setAddressSlot
Sets an address data_ located at slot_.
function _setAddressSlot(bytes32 slot_, address data_) internal;_getSigsSlot
Returns an SigsSlot with member value located at slot.
function _getSigsSlot(bytes32 slot_) internal pure returns (SigsSlot storage _r);_setImplementationSigs
Sets new implementation and adds mapping from implementation to sigs and sig to implementation.
function _setImplementationSigs(address implementation_, bytes4[] memory sigs_) internal;_removeImplementationSigs
Removes implementation and the mappings corresponding to it.
function _removeImplementationSigs(address implementation_) internal;_getImplementationSigs
Returns bytes4 sigs from implementation address. If implemenatation is not registered then returns empty array.
function _getImplementationSigs(address implementation_) internal view returns (bytes4[] memory);_getSigImplementation
Returns implementation address from bytes4 sig. If sig is not registered then returns address(0).
function _getSigImplementation(bytes4 sig_) internal view returns (address implementation_);_getAdmin
Returns the current admin.
function _getAdmin() internal view returns (address);_getDummyImplementation
Returns the current dummy-implementation.
function _getDummyImplementation() internal view returns (address);_setAdmin
Stores a new address in the EIP1967 admin slot.
function _setAdmin(address newAdmin_) internal;_setDummyImplementation
Stores a new address in the EIP1967 implementation slot.
function _setDummyImplementation(address newDummyImplementation_) internal;Structs
