Cargo Features

realtime has no features set by default.

[dependencies]
realtime = { version = "0.1.1", features = ["preempt", "rtai", "xenomai"] }
preempt = rt-thread
rtai = rt-rtai
xenomai = rt-xenomai

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.

rt-rtai rtai?
rt-thread preempt?
rt-xenomai xenomai?
