Cargo Features

Sampi has no features set by default.

[dependencies]
sampi = { version = "0.4.0", features = ["wasm"] }
wasm = js-sys

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.
