Struct VtxoStatusChallenge

pub struct VtxoStatusChallenge;

Challenge for proving ownership of a VTXO when querying its status.

This is the simplest challenge - it only commits to the VTXO ID itself, with no additional challenge data or context. It proves the user controls the VTXO and is authorised to query its status.

No additional unique or random challenge data is necessary here. We’re not concerned with guarding against “replay” attacks as this challenge is for informational purposes and knowledge of this proof by a third party would indicate some kind of prior privacy leak for the user.

A malicious third party that can access this signed message would only be able to query the status of this specific VTXO.

Implementations

impl VtxoStatusChallenge

pub fn new() -> 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 VtxoStatusChallenge

fn clone(&self) -> VtxoStatusChallenge

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Hash for VtxoStatusChallenge

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 VtxoStatusChallenge

fn cmp(&self, other: &VtxoStatusChallenge) -> 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 VtxoStatusChallenge

fn eq(&self, other: &VtxoStatusChallenge) -> 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 VtxoStatusChallenge

fn partial_cmp(&self, other: &VtxoStatusChallenge) -> 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.
