Cargo Features

wgpu-types has no features set by default.

wgpu-types = { version = "0.19.2", features = ["trace", "replay", "strict_asserts", "fragile-send-sync-non-atomic-wasm"] }
trace = serde
replay = serde

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.
