Cargo Features

[dependencies]
char-lex = { version = "1.0.5", default-features = false, features = ["export_derive"] }
default = export_derive

The export_derive feature is set by default whenever char-lex is added without default-features = false somewhere in the dependency tree.

export_derive default = char-lex-macro

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.
