Cargo Features

duchess = { version = "0.1.8", default-features = false, features = ["dylibjvm"] }
default = dylibjvm

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

dylibjvm default = java-locator, libloading

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.

java-locator dylibjvm
libloading dylibjvm
