Cargo Features

[dependencies]
sfkv = { version = "0.1.0", default-features = false, features = ["postcard-values"] }
default = postcard-values

The postcard-values feature is set by default whenever sfkv is added without default-features = false somewhere in the dependency tree.

postcard-values default = postcard, serde

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.
