Struct FFTMultiplier 

pub struct FFTMultiplier;

Fallback FFT multiplier for no_std environments

This implementation provides API compatibility when the std feature is not available. It falls back to basic schoolbook multiplication since FFT requires trigonometric functions and complex arithmetic which are not available in no_std.

Implementations

impl FFTMultiplier

pub const fn new() -> Self

Create a new FFT multiplier (no_std fallback)

Returns

A new FFTMultiplier instance that uses schoolbook multiplication

pub fn multiply_big_ints( &self, a: &BigInt, b: &BigInt, ) -> Result<BigInt, MathError>

Multiply using schoolbook multiplication in no_std

Since FFT requires std features for trigonometric functions, this falls back to basic BigInt multiplication.

Arguments

• a - First integer to multiply
• b - Second integer to multiply

Returns

The product a * b
