Trait Implementations

impl<'a, TXGRAPH> SealMedium<'a, TxoutSeal<'a, TXGRAPH>> for TXGRAPH where
    TXGRAPH: TxGraph + TxResolve, 

type PublicationId = ShortId

Publication id that may be used for referencing publication of witness data in the medium. By default set (), so SealMedium may not implement publication id and related functions

type Error = Error

Error type that contains reasons of medium access failure

fn define_seal(
    &'a self,
    seal_definition: &OutPoint
) -> Result<TxoutSeal<'_, TXGRAPH>, Self::Error>

Creates a single-use-seal having type of implementation-specific generic parameter SEAL.

fn get_seal_status(
    &self,
    seal: &TxoutSeal<'_, TXGRAPH>
) -> Result<SealStatus, Self::Error>

Checks the status for a given seal in proof-of-publication medium

fn publish_witness(
    &mut self,
    _witness: &SEAL::Witness
) -> Result<Self::PublicationId, SealMediumError<Self::Error>>

Publishes witness data to the medium. Function has default implementation doing nothing and returning SealMediumError::PublicationIdNotSupported error.

fn get_witness_publication_id(
    &self,
    _witness: &SEAL::Witness
) -> Result<Option<Self::PublicationId>, SealMediumError<Self::Error>>

Returns Self::PublicationId for a given witness, if any; the id is returned as an option. Function has default implementation doing nothing and just returning SealMediumError::PublicationIdNotSupported error.

fn validate_publication_id(
    &self,
    _publication_id: &Self::PublicationId
) -> Result<bool, SealMediumError<Self::Error>>

Validates whether a given publication id is present in the medium. Function has default implementation doing nothing and returning SealMediumError::PublicationIdNotSupported error.

impl<'a, RESOLVER> SingleUseSeal for TxoutSeal<'a, RESOLVER> where
    RESOLVER: TxResolve, 

type Witness = Witness

Associated type for the witness produced by the single-use-seal close procedure

type Definition = OutPoint

Type that contains seal definition

type Error = Error

Closing and verification errors

fn close(&self, over: &Message) -> Result<Self::Witness, Self::Error>

NB: Closing of the seal MUST not change the internal state of the seal itself; all the data produced by the process must be placed into the returned Witness type

fn verify(
    &self,
    msg: &Message,
    witness: &Self::Witness
) -> Result<bool, Self::Error>
