4//! Collection of errors to be used in fastcrypto.
5//!
6//! A function should validate its arguments and return an indicative errors where needed.
7//! However, once the function is executing the cryptographic protocol/algorithm (directly/
8//! indirectly) then it should not return explicit errors as it might leak private information.
9//! In those cases the function should return the opaque, general error [FastCryptoError::GeneralOpaqueError].
10//! When in doubt, prefer [FastCryptoError::GeneralOpaqueError].
