Cargo Features

ipipe = { version = "0.11.7", default-features = false, features = ["static_pipe", "channels", "tokio_channels", "rand"] }
default = rand, static_pipe

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

static_pipe default = flurry, lazy_static
tokio_channels = tokio

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.

rand default

Enables rand ^0.5

lazy_static static_pipe
flurry static_pipe
