Function halo2_base::utils::decompose_bigint

pub fn decompose_bigint<F: BigPrimeField>(
    e: &BigInt,
    num_limbs: usize,
    bit_len: usize
) -> Vec<F>

Decomposes an immutable reference to a BigInt into num_limbs limbs of bit_len bits each and returns a Vec of BigPrimeField represented by those limbs.

Assumes bit_len < 128.

• e: immutable reference to BigInt to decompose
• num_limbs: number of limbs to decompose e into
• bit_len: number of bits in each limb
