9f75d1a6b5 the get_byte method needs to take mutable reference to self 
the reson for this is it's possible for external hardware to have some
side effect on a read.

f3f15de8cc remove memory.get_slice 
real hardware won't have the ability to dive in and grab a slice from
memory

Sam M W
4254c02f55 Remove unit test test_memory_set_bytes 
This is the right thing to do because its pass depends on
zero-initilization. Real memory will not behave this way
 2023-04-03 05:50:13 +01:00
Sam M W
131b0f312d remove get_byte_mut_ref method from Memory 
This is the right thing to do, because the actual hardware will perform
a read and then perform a write. This could have observable side effects
on a real system
