Cargo Features

[dependencies]
xts-mode = { version = "0.5.1", default-features = false, features = ["std", "openssl_tests"] }

default = std

The std feature is set by default whenever xts-mode is added without default-features = false somewhere in the dependency tree.

std default

openssl_tests = openssl

Features from optional dependencies

In crates that don't use the dep: syntax, optional dependencies automatically become Cargo features. These features may have been created by mistake, and this functionality may be removed in the future.

openssl openssl_tests?

Enables openssl

Is actually a dev-dependency enabled only for/by openssl_tests, but dev-dependencies can't be optional
