Enum StateMutability 

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

Variants

NonPayable

May read and modify state.

Payable

May receive Ether.

View

Reads state but does not modify it.

Pure

Does not read or modify state.

Trait Implementations

impl Clone for StateMutability

fn clone(&self) -> StateMutability

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for StateMutability

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for StateMutability

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for StateMutability

fn eq(&self, other: &StateMutability) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
