How should work Scan? about aries-askar HOT 5 CLOSED

Are you using Python or something else? It's not clear.

The limit applies to the entire scan, not the size of the pages returned by next (that is currently fixed at 32).

from aries-askar.

The two sqlite and postgres backends currently use this constant for the page size:

aries-askar/src/backend/db_utils.rs

Line 23 in a93ce8d

pub const PAGE_SIZE: usize = 32;

It could be added to the interface when creating a Scan, but that would be a minor breaking change to the API. Is there a reason why you are using such a small number?

askar_scan_next will return an EntryListHandle of 0 when the end of the list is reached, which is probably why you are getting the invalid handle error.

No no. I don't need so small number at all. I just used 2 as an example. I thought that the limit is a page size. Now everything is clear for me.

The issue can be closed. Thx a lot!

I'm using the Kotlin implementation. Thx for answer!

Will it be possible to change page size in future?

Are you sure about 32? Based on code I can see that the page size depends on device CPU arch (https://doc.rust-lang.org/std/primitive.usize.html). You are using there usize.
