Cargo Features

UBJSON has no features set by default.

[dependencies]
ubjson = { version = "0.1.0", features = ["impl-serde"] }
impl-serde = serde, serde_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.

serde impl-serde?
serde_json impl-serde?
