Unable to generate parameters &[&ToSql] dynamicaly. Please help!

[andriy-viyatyk]

Hello.

I am trying to write some object model for my project and stuck on errors like "temporary/borrowed value does not live long enough" in attempts to generate parameters &[&ToSql]. The only way I found is to implement ToSql trait for my own types, but for that I need to make ToColumnData and ColumnData public.

Rust.zip
Here is an archive with simple example of object model. The "obj_model_test" inside works, but contains commented String field and related code. If remove the comments compilation will fail. Similar problem I have with Uuid fields (uuid crate) and some custom field that serializes to binary.

Do you know some way to create parameters not just from local variables ?

Thanks in advance for any help.

I'm not sure to be honest. Do parameters need to be included in the use statement for tiberius, maybe? Hopefully, someone who actually knows something will help you. Good Luck!

Looks like I'm also hitting this problem, in my case I'm trying to convert Vec<String> to &[&ToSql] when trying to create an select * from x where x.a in (...)
