Function soil_sum_new 

#[unsafe(no_mangle)]
pub unsafe extern "C" fn soil_sum_new(
    runtime: *mut SoilRuntime,
    type_id: u32,
    variant: *const c_char,
    payload: *const Value,
    err: *mut *mut SoilError,
) -> *mut Value

Build a sum value by variant name. payload is null for nullary variants, borrowed otherwise.

Safety

runtime is live; variant is a NUL-terminated UTF-8 string; payload is null or a valid value handle; err is null or valid.
