Cargo Features

[dependencies]
silver_surf = { version = "0.1.4", default-features = false, features = ["std-web"] }
default = std-web

The std-web feature is set by default whenever silver_surf is added without default-features = false somewhere in the dependency tree.

std-web default = stdweb

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.
