Cargo Features

[dependencies]
lalrpop-lambda = { version = "0.6.1", default-features = false, features = ["wasm"] }
default = wasm

The wasm feature is set by default whenever lalrpop-lambda is added without default-features = false somewhere in the dependency tree.

wasm default = wasm-bindgen

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.
