Cargo Features

[dependencies]
standalone-syn = { version = "0.13.0", default-features = false, features = ["full", "derive", "parsing", "printing", "visit", "visit-mut", "fold", "clone-impls", "extra-traits", "proc-macro"] }

default = clone-impls, derive, parsing, printing, proc-macro

These default features are set whenever standalone-syn is added without default-features = false somewhere in the dependency tree.

proc-macro default

Enables proc-macro of proc-macro2 ^0.2.3 and standalone-quote

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.
