Use Rust or Golang to implement a fixed term deposit interest calculator

This job is to create a Docker container that provides the following pseudo-code API. ------------- struct FixedTermDeposit: - Investment amount (INT) - Investment start date (DATE) - Investment end date (DATE) - Interest rate p.a. (FLOAT) - First payment date (DATE) - Payment schedule (CHOICE: daily, monthly, annually, at end) - Whether interest accumulates (BOOL) def get_value_during_range(FixedTermDeposit, from_date, to_date): """ Returns a time series of the value of the fixed term deposit in the given range of days. Returns: ARRAY of amounts (INT) """ def get_income_during_range(FixedTermDeposit, from_date, to_date): """ Returns a time series of the income (payout) generated by the fixed term deposit in the given range of days. Returns: ARRAY of amounts (INT) """ ------------- Requirements: - The program should be written using Rust oder Golang - The container API must return the result efficiently serialized (using XDR or protobuf) - A script must be provided to start the calculation from outside the container - Communication of the script with the container must use a fast, scalable transport mechanism (not HTTP or SPDY). grpc may be an option, but I did not do my research. To clarify, this job includes the task of modeling/programming the required logic.
