Implementations

impl RangeProof

pub fn serialize(&self) -> Vec<u8>

Serialize to bytes.

pub fn from_slice(bytes: &[u8]) -> Result<Self, Error>

Parse from byte slice.

TODO: Rename to parse (and other similar functions)

pub fn len(&self) -> usize

Get length.

pub fn is_empty(&self) -> bool

Check if it’s empty.

pub fn new<C: Signing>( secp: &Secp256k1<C>, min_value: u64, commitment: PedersenCommitment, value: u64, commitment_blinding: Tweak, message: &[u8], additional_commitment: &[u8], sk: SecretKey, exp: i32, min_bits: u8, additional_generator: Generator, ) -> Result<RangeProof, Error>

Prove that commitment hides a value within a range, with the lower bound set to min_value.

pub fn verify<C: Verification>( &self, secp: &Secp256k1<C>, commitment: PedersenCommitment, additional_commitment: &[u8], additional_generator: Generator, ) -> Result<Range<u64>, Error>

Verify that the committed value is within a range.

If the verification is successful, return the actual range of possible values.

pub fn rewind<C: Verification>( &self, secp: &Secp256k1<C>, commitment: PedersenCommitment, sk: SecretKey, additional_commitment: &[u8], additional_generator: Generator, ) -> Result<(Opening, Range<u64>), Error>

Verify a range proof proof and rewind the proof to recover information sent by its author.

Feeds this value into the given Hasher.

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

where H: Hasher, Self: Sized,

impl Ord for RangeProof

fn cmp(&self, other: &RangeProof) -> 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.

where Self: Sized,

impl PartialEq for RangeProof

fn eq(&self, other: &RangeProof) -> 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.

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

impl Serialize for RangeProof

Available on crate features serde and hashes only.

fn serialize<S: Serializer>(&self, s: S) -> Result<S::Ok, S::Error>

Serialize this value into the given Serde serializer.
