Different error types which may happen during deterministic bitcoin commitment generation procedures

Variants

Lnpbp1Commitment(Error)

Tuple Fields

0: Error

Indicates failure of applying commitment tweak to a public key

InvalidProofStructure

Unable to verify commitment due to an incorrect proof data structure

InvalidOpReturnKey

LNPBP-2 standard requires OP_RETURN-based commitments to be produced only if serialized version of a tweaked pubkey starts with 02 byte. This error indicates that the provided public key does not satisfy this condition

InvalidKeyData

Can’t deserealized public key from bitcoin script push op code

UnsupportedWitnessVersion

Wrong witness version, may be you need to upgrade used library version

LockscriptParseError

Miniscript was unable to parse provided script data; they are either invalid or miniscript library contains a bug

LockscriptContainsNoKeys

Provided script contains no keys, so commitment or its verification is impossible

LockscriptContainsUnknownHashes

Bitcoin script contains public key hashes with no matching public keys provided. Commitment procedure fails since it can’t ensure that commitment include all public key.

LockscriptKeyNotFound

Attempt to commit into LockScript has failed: the key that must contain the commitment/tweak was not found either in plain nor hash form in any of the script branches

PolicyCompilation(CompilerError)

Tuple Fields

0: CompilerError

Policy compilation error

UncompressedKey

Deterministic bitcoin commitments require use of compressed public keys

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
