This macro is a utility for working with database connection pools.
It tries to retrieve a connection from the provided pool.
If successful, the connection is returned for further use.
If there’s an error in obtaining a connection, it handles the error by immediately returning an HTTP response with an appropriate error message and status code. This macro ensures a uniform way of handling database pool errors across different parts of an Axum application.
In the spellbook_sanitize_fields macro:
- It takes any struct ($struct) and a list of fields within that struct.
- For each field, if it is an Option and currently has a value (Some), that value is sanitized using the crate::utility::sanitize_string_limit function.
- The macro is designed to be reusable for any struct with fields that need sanitizing and can handle multiple fields at once.
- This macro simplifies the process of sanitizing multiple fields in a struct, ensuring that each specified field is sanitized if it contains a value.
It reduces code repetition and improves readability by abstracting the common pattern of sanitizing multiple optional fields.
