Struct ed25519_dalek::errors::DecodingError
[−]
[src]
pub struct DecodingError(_);
Errors which may occur in the from_bytes()
constructors of PublicKey
,
SecretKey
, ExpandedSecretKey
, Keypair
, and Signature
.
There was an internal problem due to parsing the Signature
.
This error may arise due to:
- A problem decompressing
r
, a curve point, in theSignature
, or the curve point for aPublicKey
. - A problem with the format of
s
, a scalar, in theSignature
. This is only raised if the high-bit of the scalar was set. (Scalars must only be constructed from 255-bit integers.) - Being given bytes with a length different to what was expected.
