Enum StateMutability 

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

Available on crate feature dyn-abi only.

A JSON ABI function’s state mutability.

This will serialize/deserialize as the stateMutability JSON ABI field’s value, see as_json_str. For backwards compatible deserialization, see serde_state_mutability_compat.

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.

Implementations

impl StateMutability

pub fn parse(s: &str) -> Option<StateMutability>

Parses a state mutability from a string.

pub const fn as_str(self) -> Option<&'static str>

Returns the string representation of the state mutability.

pub const fn as_json_str(self) -> &'static str

Returns the string representation of the state mutability when serialized to JSON.

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<(), Error>

Formats the value using the given formatter.

impl Default for StateMutability

fn default() -> StateMutability

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for StateMutability

fn deserialize<__D>( __deserializer: __D, ) -> Result<StateMutability, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl FromStr for StateMutability

type Err = ()

The associated error which can be returned from parsing.

fn from_str( s: &str, ) -> Result<StateMutability, <StateMutability as FromStr>::Err>

Parses a string s to return a value of this type.

impl Hash for StateMutability

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for StateMutability

fn cmp(&self, other: &StateMutability) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

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.

impl PartialOrd for StateMutability

fn partial_cmp(&self, other: &StateMutability) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for StateMutability

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for StateMutability

impl Eq for StateMutability

impl StructuralPartialEq for StateMutability

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
