Cargo Features

expanse = { version = "0.3.4", default-features = false, features = ["std", "alloc", "serde_kebab_case"] }
default = std

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

std default

Enables std of num-traits

alloc = hashbrown
serde_camel_case serde_kebab_case = 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.

hashbrown alloc?

Enables hashbrown ^0.6.3

serde serde_camel_case? serde_kebab_case?
