Cargo Features

Halfbrown has no features set by default.

halfbrown = { version = "0.2.5", features = ["fxhash", "arraybackend", "serde"] }
fxhash = rustc-hash

Affects halfbrown::DefaultHashBuilder

arraybackend = arrayvec

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.

rustc-hash fxhash?
serde implicit feature

Enables serde


A generic serialization/deserialization framework

arrayvec arraybackend?
