Cargo Features

nostr-grpc has no features set by default.

[dependencies]
nostr-grpc = { version = "0.1.3", features = ["build"] }
build = tonic-build

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.
