Struct ConditionCodes 

pub struct ConditionCodes(/* private fields */);

The 6809 Condition Code register, stored as a packed byte.

#[repr(transparent)] guarantees that this type has exactly the same memory layout as a u8, making it safe to use in #[repr(C)] structs and directly accessible from JIT-emitted code.

Trait Implementations

impl Clone for ConditionCodes

fn clone(&self) -> ConditionCodes

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ConditionCodes

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

Formats the value using the given formatter.

impl Default for ConditionCodes

fn default() -> ConditionCodes

Returns the “default value” for a type.

impl Display for ConditionCodes

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

Formats the value using the given formatter.

impl PartialEq for ConditionCodes

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