Struct PaymentId

pub struct PaymentId(pub [u8; 32]);

A user-provided identifier in ChannelManager::send_payment used to uniquely identify a payment and ensure idempotency in LDK.

This is not exported to bindings users as we just use [u8; 32] directly

Tuple Fields

0: [u8; 32]

Implementations

impl PaymentId

pub const LENGTH: usize = 32usize

Number of bytes in the id.

Trait Implementations

impl Borrow<[u8]> for PaymentId

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

Immutably borrows from an owned value.

impl Clone for PaymentId

fn clone(&self) -> PaymentId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PaymentId

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

Formats the value using the given formatter.

impl Display for PaymentId

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

Formats the value using the given formatter.

impl Hash for PaymentId

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

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl LowerHex for PaymentId

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

Formats the value using the given formatter.

impl PartialEq for PaymentId

fn eq(&self, other: &PaymentId) -> 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 Readable for PaymentId

fn read<R: Read>(r: &mut R) -> Result<Self, DecodeError>

Reads a Self in from the given Read.

impl UpperHex for PaymentId

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

Formats the value using the given formatter.

impl Verification for PaymentId

fn hmac_for_offer_payment( &self, nonce: Nonce, expanded_key: &ExpandedKey, ) -> Hmac<Sha256>

Constructs an HMAC to include in OffersContext::OutboundPayment for the payment id along with the given Nonce.

fn verify_for_offer_payment( &self, hmac: Hmac<Sha256>, nonce: Nonce, expanded_key: &ExpandedKey, ) -> Result<(), ()>

Authenticates the payment id using an HMAC and a Nonce taken from an OffersContext::OutboundPayment.

impl Writeable for PaymentId

fn write<W: Writer>(&self, w: &mut W) -> Result<(), Error>

Writes self out to the given Writer.

fn encode(&self) -> Vec<u8>

Writes self out to a Vec<u8>.

fn serialized_length(&self) -> usize

Gets the length of this object after it has been serialized. This can be overridden to optimize cases where we prepend an object with its length.

impl Copy for PaymentId

impl Eq for PaymentId

impl StructuralPartialEq for PaymentId
