secp256k1 base-field arithmetic.

Trait Implementations

impl AxisExtension for PrimeFieldNumericSecp256k1

const AXIS_ADDRESS: &'static str = <PrimeFieldNumericSecp256k1 as FieldAxis>::AXIS_ADDRESS

ADR-017 content address of this axis trait. The SDK macro derives this from the trait name and method signatures.

const MAX_OUTPUT_BYTES: usize = <PrimeFieldNumericSecp256k1 as FieldAxis>::MAX_OUTPUT_BYTES

Maximum bytes any kernel of this axis returns.

fn dispatch_kernel( kernel_id: u32, input: &[u8], out: &mut [u8], ) -> Result<usize, ShapeViolation>

Dispatch the kernel identified by kernel_id against the evaluated input bytes. The implementation copies the kernel’s output into out and returns the written length.

impl Clone for PrimeFieldNumericSecp256k1

fn clone(&self) -> PrimeFieldNumericSecp256k1

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PrimeFieldNumericSecp256k1

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

Formats the value using the given formatter.

impl Default for PrimeFieldNumericSecp256k1

fn default() -> PrimeFieldNumericSecp256k1

Returns the “default value” for a type.

impl FieldAxis for PrimeFieldNumericSecp256k1

const AXIS_ADDRESS: &'static str = "https://uor.foundation/axis/FieldAxis/Secp256k1Base"

ADR-017 content address.

const MAX_OUTPUT_BYTES: usize = WIDTH

Operand byte-width (32 bytes for secp256k1).

fn add(input: &[u8], out: &mut [u8]) -> Result<usize, ShapeViolation>

(a + b) mod p — input a || b (64 bytes).

fn sub(input: &[u8], out: &mut [u8]) -> Result<usize, ShapeViolation>

(a - b) mod p — input a || b (64 bytes).

fn mul(input: &[u8], out: &mut [u8]) -> Result<usize, ShapeViolation>

(a * b) mod p — input a || b (64 bytes).

impl SubstrateTermBody for PrimeFieldNumericSecp256k1

fn body_arena() -> &'static [Term]

The Term arena the kernel decomposes to. Empty slice signals a primitive-fast-path axis whose body the implementation may evaluate through dispatch_kernel directly per ADR-055’s optional fast-path.
