Cargo Features

[dependencies]
rs-std-ext = { version = "0.3.0", default-features = false, features = ["crate-num", "long-tuple-impl"] }
default = crate-num

The crate-num feature is set by default whenever rs-std-ext is added without default-features = false somewhere in the dependency tree.

crate-num default = num

enable the num crate

long-tuple-impl

enable implementation for tuple longer than 5

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.
