Cargo Features

[dependencies]
snow = { version = "0.9.6", default-features = false, features = ["default-resolver", "nightly", "ring-resolver", "ring-accelerated", "libsodium-resolver", "libsodium-accelerated", "vector-tests", "hfs", "pqclean_kyber1024", "xchachapoly", "risky-raw-split"] }

This is slightly mumbo-jumboey, but in short:
Features with a -resolver suffix simply enables the existence of a specific resolver,
and -accelerated suffix means that this resolver will be the default used by the Builder.

default = default-resolver

The default-resolver feature is set by default whenever snow is added without default-features = false somewhere in the dependency tree.

DEPRECATED: As of 2.4.1, this feature does nothing.
