Struct Bls12_381OpsLowLevel 

Source 
pub struct Bls12_381OpsLowLevel;
Expand description

Implementation of the bls12-381 operations, intended to be used directly.

Current impl is also used as a base impl for host-call based impl. The methods impl are considered to be low-level. To actually execute bls12-381 operations separate functions defined in the builtins_common::bls12_381 must be used.
