pub fn caller_is_origin<E>() -> boolwhere
    E: Environment,
Expand description

Checks whether the caller of the current contract is the origin of the whole call stack.

Prefer this over is_contract when checking whether your contract is being called by a contract or a plain account. The reason is that it performs better since it does not need to do any storage lookups.

A return value of true indicates that this contract is being called by a plain account. and false indicates that the caller is another contract.


If the returned value cannot be properly decoded.
