impl JXLParallelRunner for ParallelRunner[src]

#[no_mangle]pub unsafe extern "C" fn runner_func(
    runner_opaque: *mut c_void,
    jpegxl_opaque: *mut c_void,
    init_func: Option<unsafe extern "C" fn(_: *mut c_void, _: u64) -> i32>,
    run_func: Option<unsafe extern "C" fn(_: *mut c_void, _: u32, _: u64)>,
    start_range: u32,
    end_range: u32
) -> JxlParallelRetCode[src]

Divide the task into chunks, then spawn a thread for each chunk. Since the library explicitly states that there is no communications between each call, we can safely ignore synchronizations.
