Cargo Features

[dependencies]
rpc-toolkit = { version = "0.2.3", default-features = false, features = ["cbor"] }
default = cbor

The cbor feature is set by default whenever rpc-toolkit is added without default-features = false somewhere in the dependency tree.

cbor default = serde_cbor

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.
