[−][src]Struct schnorrkel::vrf::VRFOutput
VRF output, possibly unverified.
Internally, we keep both RistrettoPoint
and CompressedRistretto
forms using RistrettoBoth
.
We'd actually love to statically distinguish here between inputs
and outputs, as well as whether outputs were verified, but doing
so would disrupt our general purpose DLEQ proof mechanism, so
users must be responcible for this themselves. We do however
consume by value in actual output methods, and do not implement
Copy
, as a reminder that VRF outputs should only be used once
and should be checked before usage.
Methods
impl VRFOutput

pub fn from_bytes(bytes: &[u8]) -> SignatureResult<VRFOutput>
[src]
Construct a VRFOutput
from a slice of bytes.
pub fn attach_input_hash<T>(
&self,
public: &PublicKey,

T: VRFSigningTranscript,
[src]
&self,
public: &PublicKey,
