Does the Json structure only appear when the database provider is defined?

[gohellp]

I am facing the problem of not being able to define a field of type Json<>. For some reason cargo loses this structure if no database provider is specified. Looking through the sources I have not found anything that could cause this behavior.

Here are examples of configuration Cargo.toml:

[package]
name = "testing_sqlx"
version = "0.1.0"
edition = "2024"

[dependencies]
sqlx = { version = "0.8.3", features = ["json"]}

An error is detected during the cargo check: rustc: unresolved import `sqlx::types::Json` no `Json` in `types`
But the documentation is being uploaded.

[package]
name = "testing_sqlx"
version = "0.1.0"
edition = "2024"

[dependencies]
sqlx = { version = "0.8.3", features = ["postgres"]}

No error, only complaining about unused import.

Here is code on which I tests import:

use sqlx::types::Json;

I'm not completely sure it's a bug, which is why I'm creating a QnA discussion.

It is definitely a bug. I have created #3797 to track it.

Thank you! I'll wait for the problem to be solved :D
