Struct Clang

pub struct Clang {
    pub path: PathBuf,
    pub version: Option<CXVersion>,
    pub c_search_paths: Option<Vec<PathBuf>>,
    pub cpp_search_paths: Option<Vec<PathBuf>>,
}

A clang executable.

Fields

path: PathBuf

The path to this clang executable.

version: Option<CXVersion>

The version of this clang executable if it could be parsed.

c_search_paths: Option<Vec<PathBuf>>

The directories searched by this clang executable for C headers if they could be parsed.

cpp_search_paths: Option<Vec<PathBuf>>

The directories searched by this clang executable for C++ headers if they could be parsed.

Implementations

impl Clang

pub fn find(path: Option<&Path>, args: &[String]) -> Option<Clang>

Returns a clang executable if one can be found.

If the CLANG_PATH environment variable is set, that is the instance of clang used. Otherwise, a series of directories are searched. First, if a path is supplied, that is the first directory searched. Then, the directory returned by llvm-config --bindir is searched. On macOS systems, xcodebuild -find clang will next be queried. Last, the directories in the system’s PATH are searched.

Cross-compilation

If target arguments are provided (e.g., --target followed by a target like x86_64-unknown-linux-gnu) then this method will prefer a target-prefixed instance of clang (e.g., x86_64-unknown-linux-gnu-clang for the above example).

Trait Implementations

impl Clone for Clang

fn clone(&self) -> Clang

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Clang

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
