Enum Flag 

pub enum Flag {
    C,
    Z,
    NC,
    NZ,
}

Flags relevant to the operation of the instruction.

This flag is used to specify which flag the Opcode cares about, it is not used to indicate which flags an instruction may set.

For example, Opcode::Jp(Some(Flag::NZ), 0x1234) says that the instruction is a Jp (jump) instruction that will jump to location 0x1234, if the NZ (not zero) flag is set.

Variants

C

The Carry flag.

Z

The Zero Flag.

NC

The inverse of the Carry flag.

NZ

The inverse of the Zero flag.

Trait Implementations

impl Clone for Flag

fn clone(&self) -> Flag

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Flag

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

Formats the value using the given formatter.

impl Hash for Flag

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 Flag

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