Cargo Features

[dependencies]
ccl-fxhash = { version = "3.0.0", default-features = false, features = ["std", "hashmap-core"] }
default = std

The std feature is set by default whenever ccl-fxhash is added without default-features = false somewhere in the dependency tree.

std default

Enables std of byteorder

hashmap-core = hashmap_core

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.
