Cargo Features

symbolic-demangle = { version = "12.8.0", default-features = false, features = ["cpp", "msvc", "rust", "swift"] }
default = cpp, msvc, rust, swift

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

cpp default = cpp_demangle
msvc default = msvc-demangler
rust default = rustc-demangle
swift default = cc

Features from optional dependencies

In crates that don't use the dep: syntax, optional dependencies automatically become Cargo features.
