Cargo Features

[dependencies]
runtime_cfg = { version = "0.1.0", default-features = false, features = ["std", "all", "parsing", "printing"] }

default = all

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

std all parsing?

all default = parsing, printing, std

parsing all = proc-macro2, std, syn

printing all

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.

syn parsing?

Enables syn ^0.15

proc-macro2 parsing?

Enables proc-macro2 ^0.4
