Cargo Features

[dependencies]
serp-example-ocw = { version = "0.1.0", default-features = false, features = ["std"] }
default = std

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

std default = serde

Enables std of parity-scale-codec ^1.3.4, frame-support ^2.0.1, frame-system ^2.0.1, lite-json ^0.1, sp-core ^2.0.0, sp-io ^2.0.0, sp-runtime ^2.0.0, and sp-std ^2.0.0

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.
