Cargo Features

[dependencies]
cbindgen = { version = "0.28.0", default-features = false, features = ["unstable_ir", "clap"] }
default = clap

The clap feature is set by default whenever cbindgen is added without default-features = false somewhere in the dependency tree.

unstable_ir

Affects bindgen::ir, cbindgen::bindgen

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.

clap default

Required by the binary
