Cargo Features

[dependencies]
bit-vec = { version = "0.6.3", default-features = false, features = ["std", "serde_std", "serde_no_std"] }

default = std

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

std default serde_std?

serde_std = std

Enables std of serde

serde:

Provide impls for common standard library types like Vec<T> and HashMap<K, V>.
Requires a dependency on the Rust standard library.

serde_no_std

Enables alloc of serde

serde:

Provide impls for types in the Rust core allocation and collections library including String, Box<T>, Vec<T>, and Cow<T>. This is a subset of std but may be enabled without depending on all of std.

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).
