Cargo Features

[dependencies]
electron-sys = { version = "0.4.0", default-features = false, features = ["wee_alloc"] }
default = wee_alloc

The wee_alloc feature is set by default whenever electron-sys is added without default-features = false somewhere in the dependency tree.

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.
