Enum sway_core::parse_tree::declaration::function::Purity

pub enum Purity {
    Pure,
    Impure,
}

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.
