Cargo Features

[dependencies]
typed-index-collections = { version = "3.1.0", default-features = false, features = ["std", "alloc", "serde-alloc", "serde-std"] }
default = alloc, std

These default features are set whenever typed-index-collections is added without default-features = false somewhere in the dependency tree.

std default serde-std?
alloc default serde-alloc?
serde-alloc = alloc

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.

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.

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.
