Cargo Features

[dependencies]
core-video-sys = { version = "0.1.4", default-features = false, features = ["all", "display_link", "io_suface", "opengl", "metal"] }
default = display_link, metal

These default features are set whenever core-video-sys is added without default-features = false somewhere in the dependency tree.

all = direct3d, display_link, io_suface, opengl
direct3d io_suface all?
opengl all? display_link

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](https://rust-lang.github.io/rfcs/3491-remove-implicit-features.html).
