Cargo Features

[dependencies]
pe-parser = { version = "0.6.0", default-features = false, features = ["std"] }
default = std

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

std default = clap

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.
