Struct ckb_script::TransactionScriptError

pub struct TransactionScriptError { /* private fields */ }

Script execution error with the error source information.

Implementations

impl TransactionScriptError

pub fn originating_script(&self) -> &TransactionScriptErrorSource

Orginating script for the generated error

pub fn script_error(&self) -> &ScriptError

Actual error generated when verifying script

Trait Implementations

impl Clone for TransactionScriptError

fn clone(&self) -> TransactionScriptError

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TransactionScriptError

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

Formats the value using the given formatter.

impl Display for TransactionScriptError

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

Formats the value using the given formatter.

impl Error for TransactionScriptError

It is a delibrate choice here to implement StdError directly, instead of implementing thiserror::Error on TransactionScriptError. This way, calling root_cause() on ckb_error::Error would return TransactionScriptError structure, providing us enough information to inspect on all kinds of errors generated when verifying a script.

This also means calling source() or cause() from std::error::Error on TransactionScriptError would return None values. One is expected to cast a value of std::error::Error type(possibly returned from root_cause) into concrete TransactionScriptError type, then use the defined methods to fetch originating script, as well as the actual script error. See the unit test defined at the end of this file for an example.

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

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<TransactionScriptError> for Error

fn from(error: TransactionScriptError) -> Self

Converts to this type from the input type.

impl PartialEq for TransactionScriptError

fn eq(&self, other: &TransactionScriptError) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
