Struct PedersenGadget 

Source 
pub struct PedersenGadget<C: SonobeCurve, const H: bool> { /* private fields */ }
Expand description

PedersenGadget defines the in-circuit Pedersen gadget that operates over the base field of the curve and supports canonical elliptic curve point variables as commitments, where H controls whether the scheme is hiding or not.
