Struct State

#[repr(C)]
pub struct State {
    pub program_counter: u16,
    pub accumulator: u8,
    pub x_register: u8,
    pub y_register: u8,
    pub stack_pointer: u8,
    pub status: Status,
    pub memory: [u8; 65536],
    /* private fields */
}

A full representation of the state of the emulator.

Note

This struct is quite large. It’s not advised to leave this on the stack if you have an allocator.

Fields

program_counter: u16

The current program counter of the emulator.

accumulator: u8

The current state of the accumulator in the emulator.

x_register: u8

The current state of the X register in the emulator.

y_register: u8

The current state of the Y register in the emulator.

stack_pointer: u8

The current stack pointer of the emulator.

status: Status

The emulator’s status flags.

memory: [u8; 65536]

The emulator’s memory, left as one contiguous array of bytes.

This is stored inside the struct to prevent needing an allocator, but grows the struct’s size considerably. Consider storing this struct on the heap if this is undesirable and you have one.

Trait Implementations

impl Clone for State

fn clone(&self) -> State

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for State

fn fmt(&self, fmt: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for State

fn default() -> Self

Returns the “default value” for a type.

impl Hash for State

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for State

fn eq(&self, other: &State) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
