bindgen-cfg

Specify bindgen settings using yaml.

Example

build.rs:

```rust use std::path::PathBuf;

use bindgen_cfg::BuilderExt;

fn main() { let outpath = PathBuf::from(env::var("OUTDIR").unwrap()); bindgen::builder() .header("wrapper.h") .parsecallbacks(Box::new(bindgen::CargoCallbacks)) .config("bindgen.yaml") .expect("bindgen config is present and well formed") .generate() .writetofile(outpath.join("bindings.rs")) .expect("write SPDK bindings"); } ```

bindgen.yaml:

yaml opaque: - spdk_nvme_ctrlr - spdk_nvme_ctrlr_data - spdk_nvme_qpair - spdk_nvme_ns - spdk_nvme_cpl - spdk_nvme_health_information_page - spdk_nvme_sgl_descriptor type: block: - spdk_nvme_tcp_rsp - spdk_nvme_tcp_cmd - spdk_nvmf_fabric_prop_get_rsp - spdk_nvmf_fabric_connect_rsp - spdk_nvmf_fabric_connect_cmd - spdk_nvmf_fabric_auth_send_cmd - spdk_nvmf_fabric_auth_recv_cmd block: - IPPORT_RESERVED - FP_NORMAL - FP_SUBNORMAL - FP_ZERO - FP_INFINITE - FP_NAN
