Cargo Features

[dependencies]
jsonrpc-base = { version = "0.2.0", default-features = false, features = ["std", "uuid"] }
default = std, uuid

These default features are set whenever jsonrpc-base is added without default-features = false somewhere in the dependency tree.

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.
