Possible errors in computing the signature message

Variants

Io(ErrorKind)

Could happen only by using *_encode_signing_* methods with custom writers, engines writers like the ones used in methods *_signature_hash don’t error

IndexOutOfInputsBounds

Fields

index: usize

Requested index

inputs_size: usize

Number of transaction inputs

Requested index is greater or equal than the number of inputs in the transaction

SingleWithoutCorrespondingOutput

Fields

index: usize

Requested index

outputs_size: usize

Number of transaction outputs

Using SIGHASH_SINGLE without a “corresponding output” (an output with the same index as the input being verified) is a validation failure

PrevoutsSize

There are mismatches in the number of prevouts provided compared with the number of inputs in the transaction

PrevoutIndex

Requested a prevout index which is greater than the number of prevouts provided or a Prevouts::One with different index

PrevoutKind

A single prevout has been provided but all prevouts are needed without ANYONECANPAY

WrongAnnex

Annex must be at least one byte long and the first bytes must be 0x50

InvalidSighashType(u32)

Invalid Sighash type

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

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

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

🔬 This is a nightly-only experimental API. (backtrace)

Returns a stack backtrace, if available, of where this error occurred.

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

impl From<Error> for Error

fn from(e: Error) -> Self

Converts to this type from the input type.

impl Hash for Error

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H) where
    H: Hasher, 

Feeds a slice of this type into the given Hasher.

impl Ord for Error

fn cmp(&self, other: &Error) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

Restrict a value to a certain interval.

impl PartialEq<Error> for Error

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

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

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

This method tests for !=.

impl PartialOrd<Error> for Error

fn partial_cmp(&self, other: &Error) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.
