ABI Encoding and Decoding errors.

Variants

TypeCheckFail

A typecheck detected a word that does not match the data type.

Fields

expected_type: Cow<'static, str>

The Solidity type we failed to produce.

data: String

Hex-encoded data.

Overrun

Overran deserialization buffer.

Reserve(TryReserveError)

Allocation failed.

BufferNotEmpty

Trailing bytes in deserialization buffer.

ReserMismatch

Validation reserialization did not match input.

RecursionLimitExceeded(u8)

ABI Decoding recursion limit exceeded.

InvalidEnumValue

Invalid enum value.

Fields

name: &'static str

The name of the enum.

value: u8

The invalid value.

max: u8

The maximum valid value.

InvalidLog

Could not decode an event from log topics.

Fields

name: &'static str

The name of the enum or event.

log: Box<LogData>

The invalid log.

UnknownSelector

Unknown selector.

Fields

name: &'static str

The type name.

selector: FixedBytes<4>

The unknown selector.

FromHexError(FromHexError)

Hex error.

Other(Cow<'static, str>)

Other errors.

Implementations

impl Error

pub fn custom(s: impl Into<Cow<'static, str>>) -> Self

Instantiates a new error with a static str.

pub fn type_check_fail_sig(data: &[u8], signature: &'static str) -> Self

Instantiates a new Error::TypeCheckFail with the provided data.

pub fn type_check_fail_token<T: SolType>(token: &T::Token<'_>) -> Self

Instantiates a new Error::TypeCheckFail with the provided token.

pub fn type_check_fail( data: &[u8], expected_type: impl Into<Cow<'static, str>>, ) -> Self

Instantiates a new Error::TypeCheckFail with the provided data.

pub fn unknown_selector(name: &'static str, selector: [u8; 4]) -> Self

Instantiates a new Error::UnknownSelector with the provided data.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a duplicate 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 Display for Error

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

Formats the value using the given formatter.

impl Error for Error

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<FromHexError> for Error

fn from(value: FromHexError) -> Self

Converts to this type from the input type.

impl From<TryReserveError> for Error

fn from(value: TryReserveError) -> Self

Converts to this type from the input type.

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 StructuralPartialEq for Error

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.
