Function query 

pub fn query<T: DeserializeOwned>(
    sql: &str,
    params: &[&dyn ToDbValue],
) -> VtxResult<Vec<T>>

Executes query SQL statements (SELECT) and deserializes the result into a list of target types.

Parameters

• sql: SQL string (supports ? placeholders).
• params: Array of parameters (implementing ToDbValue).

Returns

• Success: Collection of deserialized results.
• Failure: DatabaseError or SerializationError.

Notes

• The host interface returns a JSON string.
• To ensure performance, it is recommended to limit a single response to within 1MB (pagination via LIMIT is suggested).
• Generic T must implement DeserializeOwned (lifetimes are not required).
