Struct Constructor

pub struct Constructor {
    pub inputs: Vec<Param>,
    pub state_mutability: StateMutability,
}

Available on crate feature json-abi only.

A JSON ABI constructor function.

Fields

inputs: Vec<Param>

The input types of the constructor. May be empty.

state_mutability: StateMutability

The state mutability of the constructor.

Implementations

impl Constructor

pub fn parse(s: &str) -> Result<Constructor, Error>

Parses a Solidity constructor string: constructor($($inputs),*) [visibility] [s_mutability]

Note:

• the name must always be constructor
• visibility is ignored

Examples

assert_eq!(
    Constructor::parse("constructor(uint foo, address bar)"),
    Ok(Constructor {
        inputs: vec![Param::parse("uint foo").unwrap(), Param::parse("address bar").unwrap()],
        state_mutability: StateMutability::NonPayable,
    }),
);

Trait Implementations

impl Clone for Constructor

fn clone(&self) -> Constructor

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Constructor

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Constructor

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<'a> From<&'a Constructor> for AbiItem<'a>

fn from(item: &'a Constructor) -> AbiItem<'a>

Converts to this type from the input type.

impl From<Constructor> for AbiItem<'_>

fn from(item: Constructor) -> AbiItem<'_>

Converts to this type from the input type.

impl FromStr for Constructor

type Err = Error

The associated error which can be returned from parsing.

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

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

impl Hash for Constructor

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 JsonAbiExt for Constructor

fn abi_encode_input(&self, values: &[DynSolValue]) -> Result<Vec<u8>, Error>

ABI-encodes the given values, prefixed by this item’s selector, if any.

fn abi_encode_input_raw(&self, values: &[DynSolValue]) -> Result<Vec<u8>, Error>

ABI-encodes the given values, without prefixing the data with the item’s selector.

fn abi_decode_input( &self, data: &[u8], validate: bool, ) -> Result<Vec<DynSolValue>, Error>

ABI-decodes the given data according to this item’s input types.

impl PartialEq for Constructor

fn eq(&self, other: &Constructor) -> 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 Serialize for Constructor

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 Eq for Constructor

impl StructuralPartialEq for Constructor

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.
