public interface EdgeChunkWriter
extends com.alibaba.fastffi.CXXPointer
```
The writer for edge (adj list, offset and property group) chunks.
Notes: For each writing operation, a validate_level could be set, which will be used to validate the data before writing. The validate_level could be:
ValidateLevel::default_validate: to use the validate_level of the writer, which set through the constructor or the SetValidateLevel method;
ValidateLevel::no_validate: without validation;
ValidateLevel::weak_validate: to validate if the vertex/edge count or vertex/edge chunk index is non-negative, the adj_list type is valid, the property group exists and the size of input_table is not larger than the chunk size;
ValidateLevel::strong_validate: besides weak_validate, also validate the schema of input_table is consistent with that of property group; for writing operations without input_table, such as writing vertices/edges number or copying file, the strong_validate is same as weak_validate.
