pub type StateMutability = StateMutability;

Function’s state mutability

Aliased Type

enum StateMutability {
    Pure,
    View,
    NonPayable,
    Payable,
}

Variants

Pure

Pure functions promise not to read from or modify the state.

View

View functions promise not to modify the state.

NonPayable

Nonpayable functions promise not to receive Ether.

This is the solidity default: https://docs.soliditylang.org/en/latest/abi-spec.html#json

The state mutability nonpayable is reflected in Solidity by not specifying a state mutability modifier at all.

Payable

Payable functions make no promises.
