Cargo Features

[dependencies]
adler32 = { version = "1.2.0", default-features = false, features = ["std", "rustc-dep-of-std"] }
default = std

The std feature is set by default whenever adler32 is added without default-features = false somewhere in the dependency tree.

Affects adler32::adler32

rustc-dep-of-std = compiler_builtins, core

Internal feature, only used when building as part of libstd, not part of the stable interface of this crate.

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](https://rust-lang.github.io/rfcs/3491-remove-implicit-features.html).
