Type of operation performed in a CB prefix opcode.

Variants

RotateLeft8

8-bit left rotate. Bit 7 goes to both the carry and bit 0.

RotateLeft9

9-bit left rotate. Bit 7 goes to carry and carry goes to bit 0.

RotateRight8

8-bit right rotate. Bit 0 goes to both the carry and bit 7.

RotateRight9

9-bit left rotate. Bit 0 goes to carry and carry goes to bit 7.

ShiftLeft

Shift left. Bit 7 gotes to carry, and 0 fills in Bit 0.

ShiftRight

Shift right. Bit 0 goes to carry, and 0 fills in Bit 7.

ShiftRightSignExt

Shift right with sign-extension. Bit 0 goes to carry, and Bit 7 is copied with its current value.

Swap

Swap the nybbles of the byte.

TestBit(u8)

Check if the given bit (given as an index in range 0..=7) is set in the operand.

SetBit(u8)

Sets the given bit (given as an index in range 0..=7) in the operand.

ResetBit(u8)

Clears the given bit (given as an index in range 0..=7) in the operand.

Trait Implementations

impl Clone for CBOperation

fn clone(&self) -> CBOperation

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CBOperation

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

Formats the value using the given formatter.

impl Display for CBOperation

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

Formats the value using the given formatter.

impl Ord for CBOperation

fn cmp(&self, other: &CBOperation) -> 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 CBOperation

fn eq(&self, other: &CBOperation) -> 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 CBOperation

fn partial_cmp(&self, other: &CBOperation) -> 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.
