Struct Revert

pub struct Revert {
    pub reason: String,
}

Represents a standard Solidity revert. These are thrown by revert(reason) or require(condition, reason) statements in Solidity.

Fields

reason: String

The reason string, provided by the Solidity contract.

Implementations

impl Revert

pub fn reason(&self) -> &str

Returns the revert reason string, or "<empty>" if empty.

Trait Implementations

impl AsRef<str> for Revert

fn as_ref(&self) -> &str

Converts this type into a shared reference of the (usually inferred) input type.

impl Borrow<str> for Revert

fn borrow(&self) -> &str

Immutably borrows from an owned value.

impl Clone for Revert

fn clone(&self) -> Revert

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Revert

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

Formats the value using the given formatter.

impl Display for Revert

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

Formats the value using the given formatter.

impl Error for Revert

Available on crate feature std only.

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<&str> for Revert

fn from(value: &str) -> Self

Converts to this type from the input type.

impl<T> From<Revert> for ContractError<T>

fn from(value: Revert) -> Self

Converts to this type from the input type.

impl<T> From<Revert> for RevertReason<T>

Converts a Revert into a RevertReason<T>.

fn from(revert: Revert) -> Self

Converts to this type from the input type.

impl From<Revert> for String

fn from(value: Revert) -> Self

Converts to this type from the input type.

impl From<String> for Revert

fn from(reason: String) -> Self

Converts to this type from the input type.

impl Hash for Revert

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 Revert

fn eq(&self, other: &Revert) -> 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 SolError for Revert

const SIGNATURE: &'static str = "Error(string)"

The error’s ABI signature.

const SELECTOR: [u8; 4] = _

The error selector: keccak256(SIGNATURE)[0..4]

type Parameters<'a> = (String,)

The underlying tuple type which represents the error’s members.

type Token<'a> = (PackedSeqToken<'a>,)

The corresponding TokenSeq type.

fn new(tuple: <Self::Parameters<'_> as SolType>::RustType) -> Self

Convert from the tuple type used for ABI encoding and decoding.

fn tokenize(&self) -> Self::Token<'_>

Convert to the token type used for EIP-712 encoding and decoding.

fn abi_encoded_size(&self) -> usize

The size of the error params when encoded in bytes, without the selector.

fn abi_decode_raw(data: &[u8], validate: bool) -> Result<Self>

ABI decode this call’s arguments from the given slice, without its selector.

fn abi_decode(data: &[u8], validate: bool) -> Result<Self>

ABI decode this error’s arguments from the given slice, with the selector.

fn abi_encode_raw(&self, out: &mut Vec<u8>)

ABI encode the error to the given buffer without its selector.

fn abi_encode(&self) -> Vec<u8>

ABI encode the error to the given buffer with its selector.

impl<T> TryFrom<ContractError<T>> for Revert

type Error = ContractError<T>

The type returned in the event of a conversion error.

fn try_from(value: ContractError<T>) -> Result<Self, Self::Error>

Performs the conversion.
