Cargo Features

[dependencies]
hala-sync = { version = "0.1.6", default-features = false, features = ["trace_lock", "use_parking_lot"] }
default = trace_lock, use_parking_lot

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

trace_lock default
use_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.
