function accesses(
address
)
external
returns (
bytes32[] memory reads,
bytes32[] memory writes
);
描述
获取在地址上已读取(reads
)或已写入(writes
)的所有存储槽。
请注意,必须首先调用 record
。
ℹ️ 注意
每次写入也算作额外的读取。
示例
/// contract NumsContract {
/// uint256 public num1 = 100; // slot 0
/// uint256 public num2 = 200; // slot 1
/// }
vm.record();
numsContract.num2();
(bytes32[] memory reads, bytes32[] memory writes) = vm.accesses(
address(numsContract)
);
emit log_uint(uint256(reads[0])); // 1
