Enum RevertReason 

pub enum RevertReason<T> {
    ContractError(ContractError<T>),
    RawString(String),
}

Represents the reason for a revert in a smart contract.

This enum captures two possible scenarios for a revert:

• ContractError: Contains detailed error information, such as a specific Revert or Panic error.

• RawString: Represents a raw string message as the reason for the revert.

Variants

ContractError(ContractError<T>)

A detailed contract error, including a specific revert or panic error.

RawString(String)

Represents a raw string message as the reason for the revert.

Implementations

impl<T: SolInterface> RevertReason<T>

where Self: From<ContractError<Infallible>>,

pub fn decode(out: &[u8]) -> Option<Self>

Decodes and retrieves the reason for a revert from the provided output data.

This method attempts to decode the provided output data as a generic contract error or a UTF-8 string (for Vyper reverts).

If successful, it returns the decoded revert reason wrapped in an Option.

If both attempts fail, it returns None.

impl<T: SolInterface + Display> RevertReason<T>

pub fn to_string(&self) -> String

Returns the reason for a revert as a string.

impl<T> RevertReason<T>

pub fn as_raw_error(&self) -> Option<&str>

Returns the raw string error message if this type is a RevertReason::RawString

pub const fn as_contract_error(&self) -> Option<&ContractError<T>>

Returns the ContractError if this type is a RevertReason::ContractError

pub const fn is_revert(&self) -> bool

Returns true if self matches Revert.

pub const fn is_panic(&self) -> bool

Returns true if self matches Panic.

pub const fn is_custom_error(&self) -> bool

Returns true if self matches CustomError.

Trait Implementations

impl<T: Clone> Clone for RevertReason<T>

fn clone(&self) -> RevertReason<T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug> Debug for RevertReason<T>

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

Formats the value using the given formatter.

impl<T: Display> Display for RevertReason<T>

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

Formats the value using the given formatter.

impl<T> From<ContractError<T>> for RevertReason<T>

Converts a ContractError<T> into a RevertReason<T>.

fn from(error: ContractError<T>) -> 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<T> From<String> for RevertReason<T>

fn from(raw_string: String) -> Self

Converts to this type from the input type.

impl<T: PartialEq> PartialEq for RevertReason<T>

fn eq(&self, other: &RevertReason<T>) -> 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.
