Module sp_crypto_ec_utils::ed_on_bls12_381_bandersnatch::host_calls

Interfaces for working with Arkworks Ed-on-BLS12-381-Bandersnatch elliptic curve related types from within the runtime.

All types are (de-)serialized through the wrapper types from the ark-scale trait, with ark_scale::{ArkScale, ArkScaleProjective}.

ArkScale’s Usage generic parameter is expected to be set to “not-validated” and “not-compressed”.
