Cargo Features

Revault_tx has no features set by default.

revault_tx = { version = "0.5.0", features = ["use-serde", "fuzz"] }
use-serde = serde
fuzz = fastrand, serde_json

Features from optional dependencies

In crates that don't use the dep: syntax, optional dependencies automatically become Cargo features.

serde use-serde?
fastrand fuzz?

Enables fastrand ^1.4.0

For the 'fuzz' feature to have access to the dev-dependencies too

serde_json fuzz?
