Struct Acknowledgement 

pub struct Acknowledgement(/* private fields */);

Unverified packet acknowledgement.

This acknowledgement can be serialized and deserialized to be sent over the wire.

To retrieve useful data, it has to be verified using the public key of its sender.

Implementations

impl Acknowledgement

pub fn verify( self, sender_node_key: &OffchainPublicKey, ) -> Result<VerifiedAcknowledgement, CoreTypesError>

Attempts to verify the acknowledgement given the sender_node_key that sent the acknowledgement.

pub fn verify_batch<I>( acknowledgements: I, ) -> Vec<Result<VerifiedAcknowledgement, CoreTypesError>>

where I: IntoIterator<Item = (OffchainPublicKey, Acknowledgement)>,

Performs batch verification of acknowledgements received from given senders.

For batches of sizes smaller than MIN_BATCH_SIZE or for iterators with an unknown lower bound of size, the regular sequential verification of each signature is always performed.

For larger batches, this method makes use of the EdDSA batch signature verification algorithm, which more effectively verifies the batch. This is faster than verifying the signatures individually. However, it comes at a cost of not knowing which signature was invalid in the case of a failure.

This method first tries to verify the batch using the batch signature verification, returning a fast successful verification result quickly.

If one or more of the acknowledgements in the batch were invalid, it preforms individual checks for each signature in the batch, returning the vector of results.

These individual signature checks could be sequential or parallel if the rayon feature is enabled.

Trait Implementations

impl AsRef<[u8]> for Acknowledgement

fn as_ref(&self) -> &[u8]

Converts this type into a shared reference of the (usually inferred) input type.

impl BytesRepresentable for Acknowledgement

const SIZE: usize = 96usize

Size of the encoded byte array.

fn into_boxed(self) -> Box<[u8]>

Convenience function to copy this type’s binary representation into a Box.

impl Clone for Acknowledgement

fn clone(&self) -> Acknowledgement

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Acknowledgement

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Acknowledgement

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Acknowledgement

fn eq(&self, other: &Acknowledgement) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Acknowledgement

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<&[u8]> for Acknowledgement

type Error = GeneralError

The type returned in the event of a conversion error.

fn try_from( value: &[u8], ) -> Result<Acknowledgement, <Acknowledgement as TryFrom<&[u8]>>::Error>

Performs the conversion.
