Cargo Features

redust-resp has no features set by default.

[dependencies]
redust-resp = { version = "0.2.5", features = ["codec"] }
codec = tokio-util

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.
