Cargo Features

Envelope has no features set by default.

[dependencies]
envelope = { version = "0.8.1", features = ["serde_serialization"] }
serde_serialization = 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.
