/// A trait for parsing primitive types from foreign bindings.
///
/// This trait is used to parse primitive types from foreign provided values. For example, parsing
/// a stringified address into an `Address` type.
///
/// # Examples
/// ```rust,ignore
/// let address = Address::parse_from_ffi("0x1234567890abcdef", "address");
/// ```
///
/// # Errors
/// - `PrimitiveError::InvalidInput` if the provided string is not a valid address.
