Module input_buffer 

The InputBuffer contains a history of the ActionState for each tick.

It is used for several purposes:

• the client’s inputs for tick T must arrive before the server processes tick T, so they are stored in the buffer until the server processes them. The InputBuffer can be updated efficiently by receiving a list of ActionDiffs compared from an initial ActionState
• to implement input-delay, we want a button press at tick t to be processed at tick t + delay on the client. Therefore, we will store the computed ActionState at tick t + delay, but then we load the ActionState at tick t from the buffer

Structs

InputBuffer

Buffer that stores a value (usually Inputs) for the last few ticks.

Enums

Compressed

We use this structure to efficiently compress the inputs that we send to the server
