Struct Error

pub struct Error {
    pub name: String,
    pub inputs: Vec<Param>,
}

A JSON ABI error.

Fields

name: String

The name of the error.

inputs: Vec<Param>

A list of the error’s components, in order.

Implementations

impl Error

pub fn parse(s: &str) -> Result<Self>

Parses a Solidity error signature string: $(error)? $name($($inputs),*)

If you want to parse a generic Human-Readable ABI string, use AbiItem::parse.

Examples

Basic usage:

assert_eq!(
    Error::parse("foo(bool bar)"),
    Ok(Error { name: "foo".to_string(), inputs: vec![Param::parse("bool bar").unwrap()] }),
);

pub fn signature(&self) -> String

Computes this error’s signature: $name($($inputs),*).

This is the preimage input used to compute the selector.

pub fn selector(&self) -> Selector

Computes this error’s selector: keccak256(self.signature())[..4]

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Error

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Error

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

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

fn from(item: &'a Error) -> Self

Converts to this type from the input type.

impl From<Error> for AbiItem<'_>

fn from(item: Error) -> Self

Converts to this type from the input type.

impl FromStr for Error

type Err = Error

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

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

impl Hash for Error

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

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 PartialEq for Error

fn eq(&self, other: &Error) -> 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 Error

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
