Struct Signature 

pub struct Signature {
    pub s: Scalar,
    pub e: Scalar,
}

Schnorr signature over the ECgFp5 curve.

s and e are canonical scalars (< n). Wire format is s_le || e_le.

Fields

s: Scalar

s = k - e * sk component.

e: Scalar

e = H(r || H(m)) component reduced into the scalar field.

Implementations

impl Signature

pub fn to_le_bytes(&self) -> [u8; 80]

Encode to the canonical 80-byte little-endian layout s_le || e_le.

pub fn from_le_bytes_reduce(bytes: [u8; 80]) -> Self

Decode an 80-byte signature, reducing each scalar limb sequence modulo the group order if it exceeds the canonical range.

Mirrors the Go reference’s SigFromBytes semantics: non-canonical encodings are accepted and reduced. The verification routine performs the actual canonicality / membership check.

pub fn is_canonical(&self) -> bool

Test whether both scalar components are canonical (< n).

Trait Implementations

impl Clone for Signature

fn clone(&self) -> Signature

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Signature

impl Debug for Signature

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

Formats the value using the given formatter.

impl Eq for Signature

impl Hash for Signature

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 PartialEq for Signature

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