Cargo Features

futures-signals = { version = "0.3.33", default-features = false, features = ["debug", "serde"] }
default = debug, serde

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

debug default = log

Affects signal::SignalExt.debug, signal::SignalDebug, signal_vec::SignalVecExt.debug, signal_vec::SignalVecDebug

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.
