Struct SealWitness

pub struct SealWitness<Seal>
where
    Seal: SingleUseSeal,
{
    pub published: <Seal as SingleUseSeal>::PubWitness,
    pub client: <Seal as SingleUseSeal>::CliWitness,
    /* private fields */
}

Seal closing witness, consisting of published and client-side parts.

The seal closing witness commits to the specific SingleUseSeal protocol implementation via its Seal generic parameter.

Fields

published: <Seal as SingleUseSeal>::PubWitness

The published part of the single-use seal closing witness.

client: <Seal as SingleUseSeal>::CliWitness

The client-side part of the single-use seal closing witness.

Implementations

impl<Seal> SealWitness<Seal>

where Seal: SingleUseSeal,

pub fn new( published: <Seal as SingleUseSeal>::PubWitness, client: <Seal as SingleUseSeal>::CliWitness, ) -> SealWitness<Seal>

Construct seal closing withness out of published and client-side components.

pub fn verify_seal_closing( &self, seal: impl Borrow<Seal>, message: <Seal as SingleUseSeal>::Message, ) -> Result<(), SealError<Seal>>

Verify that a single seal is correctly closed over the message using the current seal closing witness.

This is the implementation of the single-use seals verigy procedure.

If you have multiple seals closed over the same message, consider calling Self::verify_seals_closing.

pub fn verify_seals_closing( &self, seals: impl IntoIterator<Item = impl Borrow<Seal>>, message: <Seal as SingleUseSeal>::Message, ) -> Result<(), SealError<Seal>>

Verify that all the seals from a set of seals are correctly closed over the single message using the current seal closing witness.

This is the implementation of the single-use seals verigy procedure.

If you have just a single seal, consider calling Self::verify_seal_closing.

fn clone(&self) -> SealWitness<Seal>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<Seal> Debug for SealWitness<Seal>

where Seal: Debug + SingleUseSeal, <Seal as SingleUseSeal>::PubWitness: Debug, <Seal as SingleUseSeal>::CliWitness: Debug,

where Seal: SingleUseSeal, <Seal as SingleUseSeal>::PubWitness: Serialize + for<'d> Deserialize<'d>, <Seal as SingleUseSeal>::CliWitness: Serialize + for<'d> Deserialize<'d>,

fn deserialize<__D>( __deserializer: __D, ) -> Result<SealWitness<Seal>, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<Seal> Hash for SealWitness<Seal>

where Seal: Hash + SingleUseSeal, <Seal as SingleUseSeal>::PubWitness: Hash, <Seal as SingleUseSeal>::CliWitness: Hash,

fn hash<__H>(&self, state: &mut __H)

impl<Seal> PartialEq for SealWitness<Seal>

where Seal: PartialEq + SingleUseSeal, <Seal as SingleUseSeal>::PubWitness: PartialEq, <Seal as SingleUseSeal>::CliWitness: PartialEq,

fn eq(&self, other: &SealWitness<Seal>) -> bool
