Market Simulator

A side project about a "simple" market simulator, originally made to help in a D&D campaign by giving some sort of realness to the market and to get comfortable with Rust.

TODO

• Decide solution to beginning time problem:
  • Solution 1:
    • Add beginning time field to Company struct and Companies Table
      • Pros:
        • State only depends on saved data, more specifically updates only depend on "local" data, easier to parallelize?
        • Bookkeeping is "simple", given a active company, current time = last time in ID_History (or equivalent) + company beginning time.
      • Cons:
        • It means the Company struct gets more complexity and it needs have more data.
        • More memory usage
    • Solution 2:
      • Add global time
        • Pros:
          • Super easy and light
          • Uses just one variable which only updates at the end of each update cycle.
• Finish io
  • Finish sql.rs
    • Check that sql.rs uses specified format (see SQL Table Specification)
  • Finish stdio.rs
    • Create format?
    • Specify format
    • Code specified format
• Add Testing!!!!!!!!!!!
• Redo main.rs
• Add documentation
• Check sim.rs "correctness" (i.e. specify expected behaviour in documentation and check it behaves as expected)
  • Solve spiral of death problem
  • Add queue of new companies? Or a mechanism to add created companies to the simulation in an automatic and natural way (polish and simplify idea)
• Add Events and Event log, which affect the market.
• Maybe add multiple markets and how they interact? (In a macro way, based on geographic distance or the time information travels from one market to another)
• Create a GUI?
