Function LLVMStructTypeInContext 

pub unsafe extern "C" fn LLVMStructTypeInContext(
    C: LLVMContextRef,
    ElementTypes: *mut LLVMTypeRef,
    ElementCount: c_uint,
    Packed: LLVMBool,
) -> LLVMTypeRef

Create a new structure type in a context.

A structure is specified by a list of inner elements/types and whether these can be packed together.
