Cargo Features

[dependencies]
puzz-service = { version = "0.1.0", default-features = false, features = ["alloc", "util"] }
default = alloc

The alloc feature is set by default whenever puzz-service is added without default-features = false somewhere in the dependency tree.

alloc default util?
util = alloc, futures-util, pin-project-lite

Affects puzz-service::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.

pin-project-lite util?
futures-util util?
