Cargo Features

[dependencies]
redox_syscall = { version = "0.5.8", default-features = false, features = ["std", "rustc-dep-of-std", "userspace"] }
default = userspace

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

rustc-dep-of-std = core

Enables rustc-dep-of-std of bitflags

userspace default

Affects x86::syscall4, x86::syscall5, redox_syscall::call

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.
