Struct registerMappingSstoreHookReturn 

pub struct registerMappingSstoreHookReturn {}

Registers a callback after exact mapping-element SSTOREs rooted at rootSlot in target’s effective storage account.

The callback signature is function(address account, bytes32 computedSlot, bytes32 rootSlot, bytes32[] keys, bytes32 oldValue, bytes32 newValue) external; keys are raw words in root-to-leaf order. Only complete 64-byte Keccak chains observed after the latest mapping hook registration for target in the current top-level execution match; provenance is cleared between top-level executions. Resolution follows the complete chain to its terminal root and ignores registered intermediate hashes. Offsets, incomplete or unknown chains, hashes computed before registration or in an earlier top-level execution, and source layouts do not match. The contract that calls this cheatcode receives the callback. Registration persists across reverts and replaces the same target/root callback; callback state rolls back with its enclosing context, callback reverts propagate, and hooks are suppressed throughout callback subtrees. The callback must authenticate msg.sender == address(vm) to prevent external spoofing. Raw and mapping SSTORE hooks conflict per target, while multiple mapping roots may be registered. Container type for the return parameters of the registerMappingSstoreHook(address,bytes32,bytes4) function.
