A Rust port of the TOY machine simulator, as described and explained by Sedgewick and Wayne. Their original implementation can be found at Toy.java.
All of their provided examples work as intended and can be found in the examples folder.
The simplest example is add.toy:
// add.toy
// Input: Stored in memory location 00 and 01
// Output: Sum of two integers saved in memory location 02

00: 0008 8
01: 0005 5
10: 8A00 R[A] <- mem[00]
11: 8B01 R[B] <- mem[01]
12: 1CAB R[C] <- R[A] + R[B]
13: 9C02 mem[02] <- R[C]
14: 0000 halt
To run the simulator:
$ cargo run examples/add.toy
