Cargo Features

cc-traits = { version = "2.0.0", default-features = false, features = ["alloc", "nightly", "all-impls"] }
default = alloc, std

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

std alloc default
all-impls = ijson, serde_json, slab, smallvec

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.

slab all-impls?
smallvec all-impls?
serde_json all-impls?
ijson all-impls?
