Cargo Features

async-kvdb has no features set by default.

[dependencies]
async-kvdb = { version = "0.3.1", features = ["json", "proto"] }
json = serde, serde_json
proto = prost

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.

prost proto?
serde json?
serde_json json?
