I have a special needs, store the mapping with assembly code. thank you very for everyone who can response this question.
for example:
contract assemblyMappingTest{
mapping(address => uint) public assets;
function save(address _user, uint _amount) public
{
assets[_user] = _amount;
}
function saveWithAssembly(address _user, uint _amount) public
{
assembly {
// how to write these codes, so that it can store assets like the function "save"
}
}
}
