Cargo Features

piston2d-glium_graphics = { version = "0.94.0", default-features = false, features = ["glium_window", "check_current_window", "image"] }
default = check_current_window, glium_window, image

These default features are set whenever piston2d-glium_graphics is added without default-features = false somewhere in the dependency tree.

glium_window default = piston, pistoncore-glutin_window
check_current_window default

Features from optional dependencies

In crates that don't use the dep: syntax, optional dependencies automatically become Cargo features.
