Cargo Features

RawWindowHandle has no features set by default.

raw-window-handle = { version = "0.6.2", features = ["std", "alloc", "wasm-bindgen-0-2"] }
std wasm-bindgen-0-2? = alloc
alloc std?
wasm-bindgen-0-2 = std, wasm-bindgen

Allow conversion methods to/from WASM types using wasm-bindgen v0.2.

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.
