Enum ScriptError 

pub enum ScriptError {
    InputIndexOutOfRange {
        index: usize,
        inputs: usize,
    },
    UnknownFlag {
        name: String,

    Serialization(String),
    Verification(String),
    TaprootPrevoutsUnavailable,
    TaprootUnsupportedWitness {
        elements: usize,
    },
}

Script execution errors surfaced by the script crate.

Variants

InputIndexOutOfRange

The requested input index was not present in the transaction.

Fields

index: usize

Requested input index.

inputs: usize

Transaction input count.

UnknownFlag

A Core vector flag name was not known by this crate.

Fields

name: String

Unknown flag name.

Serialization(String)

The transaction could not be serialized for the delegated verifier.

Verification(String)

The delegated consensus verifier rejected the script.

TaprootPrevoutsUnavailable

Taproot key-path verification requires all prevouts for multi-input transactions.

TaprootUnsupportedWitness

This portable path only validates one-element Taproot key-path witnesses.

Fields

elements: usize

Number of witness elements supplied for the P2TR spend.

Trait Implementations

impl Debug for ScriptError

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

Formats the value using the given formatter.

impl Display for ScriptError

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

Formats the value using the given formatter.

impl Eq for ScriptError

impl Error for ScriptError

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 PartialEq for ScriptError

fn eq(&self, other: &ScriptError) -> 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.
