Struct FixedPointQNumeric 

pub struct FixedPointQNumeric<const INT_BITS: u32, const FRAC_BITS: u32>;

Parametric Q-format fixed-point arithmetic.

INT_BITS + FRAC_BITS ≤ 64 and INT_BITS + FRAC_BITS ≥ 1. Values are two’s-complement signed integers in the canonical 64-bit container; the INT_BITS/FRAC_BITS split governs the implicit decimal point and the multiplication re-scaling.

Trait Implementations

impl<const INT_BITS: u32, const FRAC_BITS: u32> AxisExtension for FixedPointQNumeric<INT_BITS, FRAC_BITS>

const AXIS_ADDRESS: &'static str = <FixedPointQNumeric<INT_BITS, FRAC_BITS> as FixedPointAxis>::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 = <FixedPointQNumeric<INT_BITS, FRAC_BITS> as FixedPointAxis>::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<const INT_BITS: u32, const FRAC_BITS: u32> Clone for FixedPointQNumeric<INT_BITS, FRAC_BITS>

fn clone(&self) -> FixedPointQNumeric<INT_BITS, FRAC_BITS>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<const INT_BITS: u32, const FRAC_BITS: u32> Debug for FixedPointQNumeric<INT_BITS, FRAC_BITS>

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

Formats the value using the given formatter.

impl<const I: u32, const F: u32> Default for FixedPointQNumeric<I, F>

fn default() -> Self

Returns the “default value” for a type.

impl<const INT_BITS: u32, const FRAC_BITS: u32> FixedPointAxis for FixedPointQNumeric<INT_BITS, FRAC_BITS>

const AXIS_ADDRESS: &'static str = "https://uor.foundation/axis/FixedPointAxis/Q"

ADR-017 content address.

const MAX_OUTPUT_BYTES: usize = WIDTH

Operand byte-width (fixed 8 bytes = i64 container).

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

Q-format addition: a + b. Input a || b (16 bytes).

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

Q-format subtraction: a - b. Input a || b (16 bytes).

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

Q-format multiplication with bias-aware re-scaling by F fraction bits.

impl<const INT_BITS: u32, const FRAC_BITS: u32> SubstrateTermBody for FixedPointQNumeric<INT_BITS, FRAC_BITS>

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.

impl<const INT_BITS: u32, const FRAC_BITS: u32> Copy for FixedPointQNumeric<INT_BITS, FRAC_BITS>

impl<const INT_BITS: u32, const FRAC_BITS: u32> Sealed for FixedPointQNumeric<INT_BITS, FRAC_BITS>
