Cargo Features

[dependencies]
fractions-rs = { version = "0.1.2", default-features = false, features = ["std", "num-bigint-std", "serde"] }
default = num-bigint-std, std

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

std default

Enables std of num-integer and num-traits

num-bigint-std default

Enables std of num-bigint

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.

serde implicit feature

Enables serde

serde:

A generic serialization/deserialization framework
