Crate windows_clang 

windows-clang

The windows-clang crate scrapes C/C++ headers with libclang and emits RDL (Rust Definition Language) source - the text format understood by windows-rdl. It is the header-facing front end of the Win32 metadata pipeline: headers to RDL (this crate) to .winmd (windows-rdl).

• Getting started

Start by adding the following to your Cargo.toml file:

[dependencies.windows-clang]
version = "0.100"

Point it at one or more headers and write the resulting per-header RDL, then feed that RDL to windows_rdl::reader() to compile a .winmd:

windows_clang::clang()
    .input("Example.h")
    .output("rdl")
    .namespace("Example")
    .write_by_header()
    .unwrap();

Structs

Arch

Target architecture settings that differ between scrape passes.

Clang

Builder that generates RDL from C/C++ headers using libclang.

ScrapePlan

Multi-arch and output state layered on top of a configured Clang.

Summary

What Clang::scrape produced, for the caller’s summary output.

Constants

LIBCLANG_VERSION

Pinned libclang version; macro capture changes across major versions.

Functions

assert_libclang_version

Assert the loaded libclang matches LIBCLANG_VERSION.

clang

Creates a libclang-backed RDL generator.

clang_resource_dir

Resolve the version-matched clang -resource-dir, honoring CLANG_RESOURCE_DIR.

clang_version

Returns the loaded libclang version string.

ensure_libclang

Ensure libclang is loadable, respecting an existing LIBCLANG_PATH.

find_in_dirs

Find name in dirs, returning a forward-slashed path.

libclang_dir

Resolve or fetch the pinned host-arch libclang.dll directory without setting env vars.

nuget_package

Resolve or fetch an exact NuGet package, accepting global-cache or flat restore layouts.
