Possible errors in computing the signature message.

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.

Io(ErrorKind)

Could happen only by using *_encode_signing_* methods with custom writers, engines writers like the ones used in methods *_signature_hash do not 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 to 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 unless using SIGHASH_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.

const 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)>

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 self, demand: &mut Demand<'a>)

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

Provides type based access to context intended for error reports.

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,
    Self: Sized,

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.

const fn max(self, other: Self) -> Selfwhere
    Self: Sized,

Compares and returns the maximum of two values.

const fn min(self, other: Self) -> Selfwhere
    Self: Sized,

Compares and returns the minimum of two values.

const fn clamp(self, min: Self, max: Self) -> Selfwhere
    Self: Sized + PartialOrd<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 ==.

const 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.

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.

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

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

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

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

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

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

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

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