Cargo Features

[dependencies]
fixed-map = { version = "0.9.5", default-features = false, features = ["std", "hashbrown", "serde"] }
default = hashbrown, std

These default features are set whenever fixed-map is added without default-features = false somewhere in the dependency tree.

std default

Enables std of optional 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.

hashbrown default

Enables hashbrown ^0.13.2

serde implicit feature

Enables serde

serde:

A generic serialization/deserialization framework
