Cargo Features

[dependencies]
bk-tree = { version = "0.5.0", default-features = false, features = ["enable-fnv", "serde"] }
default = enable-fnv

The enable-fnv feature is set by default whenever bk-tree is added without default-features = false somewhere in the dependency tree.

enable-fnv default = fnv
serde

Enables serde

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.
