Struct LightningReceiveChallenge

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

Challenge for proving ownership of a VTXO when claiming a Lightning receive.

This challenge combines a payment hash with the input VTXO ID to create a unique signature proving the user controls the input VTXO and is authorised as a mitigation against liquidity denial-of-service attacks.

Implementations

impl LightningReceiveChallenge

pub fn new(value: PaymentHash) -> Self

pub fn sign_with(&self, vtxo_id: VtxoId, vtxo_keypair: Keypair) -> Signature

pub fn verify_input_vtxo_sig( &self, vtxo: &Vtxo, sig: &Signature, ) -> Result<(), Error>

Trait Implementations

impl Clone for LightningReceiveChallenge

fn clone(&self) -> LightningReceiveChallenge

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Hash for LightningReceiveChallenge

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 Ord for LightningReceiveChallenge

fn cmp(&self, other: &LightningReceiveChallenge) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for LightningReceiveChallenge

fn eq(&self, other: &LightningReceiveChallenge) -> 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 PartialOrd for LightningReceiveChallenge

fn partial_cmp(&self, other: &LightningReceiveChallenge) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
