Cargo Features

[dependencies]
libzmq-sys = { version = "0.1.8+4.3.2", default-features = false, features = ["curve", "renew-bindings", "libsodium"] }
default = curve

The curve feature is set by default whenever libzmq-sys is added without default-features = false somewhere in the dependency tree.

curve default
renew-bindings = bindgen

Renew the pre-generated libzmq bindings.

libsodium = libsodium-sys

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.

libsodium-sys libsodium?
bindgen build renew-bindings?
