[in,out]len_leftlength left in bytes

◆ get_serialized_length()

size_t Chunk_Info::get_serialized_length ( uint32_t  num_tasks)

Get the length of serialized data.

Parameters
[in]num_tasksnumber of tasks to include
Returns
length serialized chunk info

◆ init_chunk_nums()

void Chunk_Info::init_chunk_nums ( )
inline
