Cargo Features

[dependencies]
reminisce = { version = "0.9.1", default-features = false, features = ["mappings", "sdl"] }
default = libc

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

mappings = libc

Affects reminisce::mapper, reminisce::Joystick.into_mapper

sdl = sdl2

Affects reminisce::sdl

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.

sdl2 sdl?
libc default mappings?
