Struct LimbsEncoding

Source 
pub struct LimbsEncoding<const LIMBS: usize, const BITS: usize>;
Expand description

AccumulatorEncoding that encodes Accumulator into limbs.

Since in circuit everything are in scalar field, but Accumulator might contain base field elements, so we split them into limbs. The const generic LIMBS and BITS respectively represents how many limbs a base field element are split into and how many bits each limbs could have.
