Cargo Features

[dependencies]
broadcaster = { version = "1.0.0", default-features = false, features = ["default-channels", "parking-lot"] }
default = default-channels, parking-lot

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

default-channels default = futures-channel
parking-lot default = parking_lot

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.

futures-channel default-channels
parking_lot parking-lot

Enables parking_lot ^0.10.0
