Cargo Features

[dependencies]
fastutil = { version = "0.1.0", default-features = false, features = ["std", "alloc", "indexmap", "multimap", "serde", "rand", "nightly"] }
default = hash, indexmap, rand

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

std multimap?

multimap serde? = hash, std

breaks no_std

Enables multimap ^0.9

Affects fastutil::collections.MultiMap

serde

Enables serde of indexmap, serde_impl of multimap ^0.9

rand default

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.
