Struct Clang 

pub struct Clang(/* private fields */);

An empty type which prevents the use of this library from multiple threads simultaneously.

Implementations

impl Clang

pub fn new() -> Result<Clang, String>

Constructs a new Clang.

Only one instance of Clang is allowed at a time.

Failures

• an instance of Clang already exists
