Cargo Features

[dependencies]
serde-hjson = { version = "0.9.1", default-features = false, features = ["preserve_order", "unstable-testing"] }
default = preserve_order

The preserve_order feature is set by default whenever serde-hjson is added without default-features = false somewhere in the dependency tree.

preserve_order default = linked-hash-map

Enables serde_impl of linked-hash-map ^0.3.0

Affects value::Map, value::MapIntoIter

unstable-testing = clippy

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.

clippy unstable-testing?
linked-hash-map preserve_order
