Add no_std support to transcript, dalek-ff-group, ed448, ciphersuite, multiexp, schnorr, and monero-generators transcript, dalek-ff-group, ed449, and ciphersuite are all usable with no_std alone. The rest additionally require alloc. Part of #279. 2023-04-22 04:38:47 -04:00			`#![cfg_attr(not(feature = "std"), no_std)]`

Replace lazy_static with OnceLock inside monero-serai lazy_static, if no_std environments were used, effectively required always using spin locks. This resolves the ergonomics of that while adopting Rust std code. no_std does still use a spin based solution. Theoretically, we could use atomics, yet writing our own Mutex wasn't a priority. 2023-06-28 21:16:33 -04:00			`pub mod sync;`
