Cargo Features

[dependencies]
parity-hash = { version = "1.2.2", default-features = false, features = ["std", "serialize"] }
default = std

The std feature is set by default whenever parity-hash is added without default-features = false somewhere in the dependency tree.

std default

Enables std of uint ^0.3

serialize = serde, serde_derive

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 serialize?
serde_derive serialize?
