Cargo Features

[dependencies]
mosquitto-client-wrapper = { version = "0.3.1", default-features = false, features = ["bundled", "build_bindgen"] }
default = bundled

The bundled feature is set by default whenever mosquitto-client-wrapper is added without default-features = false somewhere in the dependency tree.

bundled default = anyhow, build_bindgen, cmake
build_bindgen bundled = bindgen

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.

cmake build bundled
bindgen build build_bindgen?

Enables bindgen ^0.50

anyhow build bundled
