# std shims

A crate which passes through to std when the default `std` feature is enabled,
yet provides a series of shims when it isn't.

No guarantee of one-to-one parity is provided. The shims provided aim to be sufficient for the
average case.

`HashSet` and `HashMap` are provided via `hashbrown`. Synchronization primitives are provided via
`spin` (avoiding a requirement on `critical-section`).
types are not guaranteed to be
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			`# std shims`

Expose Once within std-shims, bump spin to 0.9 This is technically a semver break due to bumping spin to 0.10, with the types from spin being directly exposed. Long-term, we should not directly expose spin but instead have our own types which are thin wrappers around spin (clearly defining our API and allowing upgrading internals without breaking semver). 2025-08-19 13:36:01 -04:00			`No guarantee of one-to-one parity is provided.
