Cargo Features

[dependencies]
uuid = { version = "1.6.1", default-features = false, features = ["std", "macro-diagnostics", "v1", "v3", "v4", "v5", "v6", "v7", "v8", "js", "rng", "fast-rng", "sha1", "md5", "borsh", "bytemuck", "serde", "slog", "zerocopy", "arbitrary"] }

default = std

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

std default

macro-diagnostics = uuid-macro-internal

v1 = atomic

NOTE: When adding new features, check the ci.yml workflow and include them where necessary (you can follow along with existing features)
