pub enum Purity {
Pure,
Reads,
Writes,
ReadsWrites,
}
Expand description
The purity of a function is related to its access of contract storage. If a function accesses or could potentially access contract storage, it is [Purity::Impure]. If a function does not utilize any any accesses (reads or writes) of storage, then it is Purity::Pure.
