@nprofile…mcwl This is not yet exposed by Diesel, but I would happily merge a PR adding support for it.
Generally speaking such a PR would need to contain:
Expose the blob_open() function on SqliteConnection by returning a SqliteBlob type holding a reference to the underlying connection. (Possibly have a read only variant as well). I'm not sure how to handle the row_id lookup there yet. Possibly just expect the user to pass in a primary key value and look up the corresponding row id internally? Maybe even expect a T: IntoUpdateTarget as for update/delete? (Allows using Identifiable or a explicit "query" like users::table.find(42))
The SqliteBlob type needs to implement Drop to call sqlite3_blob_close() if it goes out of scope
The SqliteBlob type needs to implement Write and Read using sqlite3_blob_write and sqlite3_blob_read
We likely want to expose a len() and possibly a is_empty() method based on sqlite3_blob_bytes()
We might want to define zeroblob as sql function somewhere.
Write some tests and documentation.
Overall I think that's a meaningful addition to Diesels API, although I currently do not have the capacity to implement it soon. It still would be great to have that in an feature request, that possibly helps posting the issue to This Week in Rust and similar channels to get someone to try implementing it.

My team at work is looking for a #Rust Backend developer helping us to build a database for 3D subsurface models. We are looking for a person that has programming experience and at least basic Rust knowledge. The role allows to work remotely from within the EU/EEA, UK or Switzerland.
Check out our job posting for details: https://de.indeed.com/job/rust-developer-mwd-963b6d4b49a46958
Just write me if you are interested or want to know more details. I'm happy to talk about any details of the work we are doing.

I‘m happy to be at RustWeek in Utrecht next week. I’ looking forward to teaching the Diesel workshop there. I will bring some Diesel stickers with me. If you are also there come to me to get stickers and to talk about Diesel.
