nom-kconfig 0.12.0

#![allow(clippy::result_large_err)]

//! # nom-kconfig
//!
//! A parser for kconfig files. The parsing is done with [nom](https://github.com/rust-bakery/nom).
//!
//! ```no_run

//! use std::collections::HashMap;

//! // curl https://cdn.kernel.org/pub/linux/kernel/v6.x/linux-6.4.9.tar.xz | tar -xJ -C /tmp/
//! fn main() -> Result<(), Box<dyn std::error::Error>> {
//!     let mut variables = HashMap::new();
//!     variables.insert("SRCARCH", "x86");
