Enum ExecutionError 

pub enum ExecutionError {
    FailedRefund(Error),
    NotReady,
    Precondition(String),
    Unspendable(Error),
}

Errors that can occur during transaction execution in the VM.

This enum encapsulates different types of errors that may arise, including precondition failures, unspendable errors, and failed refunds. Each variant provides context about the nature of the error, allowing for more precise error handling and debugging.

Variants

FailedRefund(Error)

Occurs when a refund operation fails after transaction execution.

NotReady

Occurs when the transaction is valid but cannot be processed at the moment, like when the nonce used is not the next one

Precondition(String)

Occurs when a precondition for transaction execution is not met.

Unspendable(Error)

Occurs when a transaction is deemed unspendable due to an error during execution.

Implementations

impl ExecutionError

pub fn precondition<T: ToString>(msg: T) -> Self

Creates a new ExecutionError with the Precondition variant.

pub fn from_spend_and_execute(inner: Error) -> Self

Creates a new ExecutionError from an existing Error happening during the spend_or_execute phase, categorizing it as Unspendable unless it’s a specific nonce not ready panic.

pub fn failed_refund(inner: Error) -> Self

Creates a new ExecutionError with the FailedRefund variant.

Trait Implementations

impl Debug for ExecutionError

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

Formats the value using the given formatter.

impl Display for ExecutionError

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

Formats the value using the given formatter.

impl Error for ExecutionError

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<TxPreconditionError> for ExecutionError

fn from(err: TxPreconditionError) -> Self

Converts to this type from the input type.
