8 bit operand. Either the source or destination of an 8 bit operation.

Variants

B

Normal register B.

C

Normal register C.

D

Normal register D.

E

Normal register E.

H

Normal register High.

L

Normal register Low.

A

Accumulator register.

AddrHL

Dereference HL.

AddrBC

Dereference BC.

AddrDE

Dereference DE.

AddrHLInc

Dereference HL then increment HL.

AddrHLDec

Dereference HL then decrement HL.

Immediate

Load value from immediate (and advance program counter). Cannot be used to store. Will panic if used as the destination operand.

AddrImmediate

Dereference a 16 bit immediate value.

AddrRelC

Dereference 0xff00 + register C.

AddrRelImmediate

Dereference 0xff00 + 8 bit immediate.

Trait Implementations

impl Clone for Operand8

fn clone(&self) -> Operand8

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Operand8

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

Formats the value using the given formatter.

impl Display for Operand8

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

Formats the value using the given formatter.

impl MicrocodeReadable for Operand8

As a MicrocodeReadable, Operand8 will result in a u8 being pushed onto the microcode stack from the appropriate source.

fn to_read(self) -> InstrBuilder

impl MicrocodeWritable for Operand8

As a MicrocodeWritable, Operand8 will result in a u8 popped off of the stack and written to the appropriate destination.

fn to_write(self) -> InstrBuilder

impl Ord for Operand8

fn cmp(&self, other: &Operand8) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Operand8

fn eq(&self, other: &Operand8) -> 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.

impl PartialOrd for Operand8

fn partial_cmp(&self, other: &Operand8) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
