Enum Error

#[non_exhaustive]
pub enum Error {
    NonMinimalPush,
    EarlyEndOfScript,
    NumericOverflow,
    UnknownSpentOutput(OutPoint),
    Serialization,
}

Ways that a script might fail. Not everything is split up as much as it could be; patches welcome if more detailed errors would help you.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

NonMinimalPush

Something did a non-minimal push; for more information see https://github.com/bitcoin/bips/blob/master/bip-0062.mediawiki#push-operators

EarlyEndOfScript

Some opcode expected a parameter but it was missing or truncated.

NumericOverflow

Tried to read an array off the stack as a number when it was more than 4 bytes.

UnknownSpentOutput(OutPoint)

Can not find the spent output.

Serialization

Can not serialize the spending transaction.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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<Infallible> for Error

fn from(never: Infallible) -> Self

Converts to this type from the input type.

impl PartialEq for Error

fn eq(&self, other: &Error) -> 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 Eq for Error
