select

Retrieves a single record from the database using a custom transformation function. This is useful when you want to use a custom transformation function instead of the FromRow trait.

Parameters

• client: Database connection object
• entity: Query parameter object (must implement SqlQuery and SqlParams traits)
• to_model: Function to convert a Row object to the target object type

Return Value

• Result<R, Error>: On success, returns the transformed object; on failure, returns Error
