Cargo Features

Lelet has no features set by default.

[dependencies]
lelet = { version = "1.2.18", features = ["tracing"] }
tracing = log

for debugging, will trace!() important event in the executor

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.
