Cargo Features

TaskExecQueue has no features set by default.

[dependencies]
task-exec-queue = { version = "0.9.3", features = ["rate"] }
rate = rate-counter

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.
