Errors which may occur while processing signatures and keypairs.

All these errors represent a failed signature when they occur in the context of verifying a sitgnature, including in deserializaing for verification. We expose the distinction among them primarily for debugging purposes.

This error may arise due to:

Variants

EquationFalse

A signature verification equation failed.

We emphasise that all variants represent a failed signature, not only this one.

PointDecompressionError

Invalid point provided, usually to verify methods.

ScalarFormatError

Invalid scalar provided, usually to Signature::from_bytes.

BytesLengthError

An error in the length of bytes handed to a constructor.

To use this, pass a string specifying the name of the type which is returning the error, and the length in bytes which its constructor expects.

Fields of BytesLengthError

name: &'static str

Identifies the type returning the error

description: &'static str

Describes the type returning the error

length: usize

Length expected by the constructor in bytes

NotMarkedSchnorrkel

Signature not marked as schnorrkel, maybe try ed25519 instead.

MuSigAbsent

There is no record of the preceeding multi-signautre protocol stage for the specified public key.

Fields of MuSigAbsent

musig_stage: MultiSignatureStage

Identifies the multi-signature protocol stage during which the error occured.

MuSigInconsistent

For this public key, there are either conflicting records for the preceeding multi-signautre protocol stage or else duplicate duplicate records for the current stage.

Fields of MuSigInconsistent

musig_stage: MultiSignatureStage

Identifies the multi-signature protocol stage during which the error occured.

duplicate: bool

Set true if the stage was reached correctly once but this duplicate disagrees.
