Cargo Features

[dependencies]
mediocore = { version = "0.1.0", default-features = false, features = ["bin"] }
default = bin

The bin feature is set by default whenever mediocore is added without default-features = false somewhere in the dependency tree.

bin default = serde_json, structopt

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.

structopt bin

Enables structopt ^0.2

serde_json bin
