Thanks! First, I'll try to bind grn_hash_size().

[myokoym]

Groonga::Hash has #size as Groonga::Table#size.
grn_hash_size() is already used in grn_table_size().

[myokoym]

Groonga::Hash has #size as Groonga::Table#size.
grn_hash_size() is already used in grn_table_size().

Should we call grn_hash_size() directly in Groonga::Hash?

I listed "needless" API.

You should not bind grn_hash_size().

[myokoym]

Oh... I was wrong. I understand "needless".
