Cargo Features

[dependencies]
merkle-rs = { version = "0.0.1", default-features = false, features = ["serde", "ring"] }
default = ring

The ring feature is set by default whenever merkle-rs 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.

serde implicit feature

Enables serde

serde:

A generic serialization/deserialization framework

ring default
