Function caller_is_root

pub fn caller_is_root<E>() -> bool
where
    E: Environment,

Checks whether the caller of the current contract is root.

Note that only the origin of the call stack can be root. Hence this function returning true implies that the contract is being called by the origin.

A return value of true indicates that this contract is being called by a root origin, and false indicates that the caller is a signed origin.

Errors

If the returned value cannot be properly decoded.
