Struct Processor

pub struct Processor { /* private fields */ }

Implementations

impl Processor

pub const MAX_USABLE_MEMORY_LEN: usize = 65_536usize

The maximum length of memory that can be addressed with CHIP-8 instructions, u16::MAX+1.

See also Self::MAX_ADDRESS

pub const MAX_ADDRESS: u16 = 65_535u16

The maximum address that can be represented with CHIP-8 instructions, u16::MAX+1.

Instruction::StoreRegisterValues and Instruction::LoadRegisterValues don’t allow access outside of this and will cause a runtime error when run with the sum of the address in special address register I and the number of the last_register greater than this. The same goes for Instruction::DrawSprite and the sprite_byte_len.

pub const SCREEN_WIDTH_BYTES: u8 = 8u8

Screen width in bytes.

pub const SCREEN_WIDTH: u8 = 64u8

Screen width in pixels.

pub const SCREEN_HEIGHT: u8 = 32u8

Screen height in pixels.

pub fn builder() -> ProcessorBuilder

pub fn start( self, ) -> (Sender<ControlEvent>, Receiver<ProcessorEvent>, JoinHandle<Result<Processor, ProcessorError>>)

pub const fn get_key_state(&self, key: Key) -> KeyState

Get the state of a key.

pub fn set_key_state(&mut self, key: Key, state: KeyState)

Set the state of a key.

pub const fn screen(&self) -> &[u8; 256]

pub fn step(&mut self) -> Result<StepOutcome, ProcessorError>

Trait Implementations

impl Debug for Processor

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

Formats the value using the given formatter.

impl Default for Processor

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for Processor

fn eq(&self, other: &Processor) -> 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.
