Enum CondCode 

pub enum CondCode {
    Always,
    Zero,
    NotZero,
    Carry,
    Greater,
    GreaterEq,
    Lesser,
    LesserEq,
}

The condition code potentially associated to a given instruction. Any instruction may either contain no condition code (Type-I Encoding) contain a limited condition code (Type-C Encoding) or an extended condition code (Type-J Encoding).

Variants

Always

Indicates that the instruction should always be executed.

Zero

Indicates that the instruction should only be executed if the zero bit is set.

NotZero

Indicates that the instruction should only be executed if the zero bit is cleared.

Carry

Indicates that the instruction should only be executed if the carry bit is set.

Greater

Indicates that the instruction should only be executed if both the negative bit is clear, and the zero bit is clear.

GreaterEq

Indicates that the instruction should only be executed if the negative bit is clear.

Lesser

Indicates that the instruction should only be executed if the negative bit is set.

LesserEq

Indicates that the instruction should only be executed if the negative bit is set, or if the zero bit is set.

Trait Implementations

impl Clone for CondCode

fn clone(&self) -> CondCode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Codable for CondCode

fn encode(&self) -> u16

Encodes the instruction or portion thereof.

fn decode(value: u16, mode: Mode) -> Option<Self>

Decodes the instruction given the current mode of execution.

impl Debug for CondCode

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

Formats the value using the given formatter.

impl Default for CondCode

fn default() -> Self

Returns the “default value” for a type.

impl Ord for CondCode

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

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

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