Cargo Features

[dependencies]
rs-sandbox = { version = "0.1.9", default-features = false, features = ["full", "core", "derive", "macros"] }
default = core

The core feature is set by default whenever rs-sandbox is added without default-features = false somewhere in the dependency tree.

full = core, derive, macros
core default full? = rs-sandbox-core
derive full? = rs-sandbox-derive
macros full? = rs-sandbox-macros

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.

rs-sandbox-core core
rs-sandbox-derive derive?
rs-sandbox-macros macros?
