Cargo Features

[dependencies]
lowestbins = { version = "1.4.1", default-features = false, features = ["simd"] }
default = simd

The simd feature is set by default whenever lowestbins is added without default-features = false somewhere in the dependency tree.

simd default = simd-json

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.
