Can you explain your memory arena?

Hello,

Can you explain your memory_arena struct?

[bagaffey]

Yeah, the struct memory_arena has 4 members.
They are:

1. CurrentBlock: this points to the current active memory block
2. MinimumBlockSize: this is the minimum block size that is allocated when more memory space is needed.
3. AllocationFlags: These are configuration flags like clear on alloc, check for overflow.
4. TempCount: This tracks the number of temporary allocations.

You can think of an arena as a region of memory where things can be allocated linearly. You won't need to individually free things later. Instead, you can reset the arena or completely discard whole blocks of it.
