Enum PCOffset

pub enum PCOffset<OFF, const N: u32> {
    Offset(Offset<OFF, N>),
    Label(Label),
}

An offset or a label.

This is used to represent PCOffset operands (such as the PCOffset9 operand in LD and ST and the PCOffset11 operand in JSR).

During the first assembly pass, the label is resolved and replaced with a regular Offset value.

Examples

LD R2, VALUE
       ~~~~~
BRz END
    ~~~
BR #-99
   ~~~~
JSR SUBROUTINE
    ~~~~~~~~~~

Variants

Offset(Offset<OFF, N>)

Label(Label)

Trait Implementations

impl<OFF: Clone, const N: u32> Clone for PCOffset<OFF, N>

fn clone(&self) -> PCOffset<OFF, N>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<OFF: Debug, const N: u32> Debug for PCOffset<OFF, N>

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

Formats the value using the given formatter.

impl<OFF, const N: u32> Display for PCOffset<OFF, N>

where Offset<OFF, N>: Display,

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

Formats the value using the given formatter.

impl<OFF: Hash, const N: u32> Hash for PCOffset<OFF, N>

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<OFF, const N: u32> Parse for PCOffset<OFF, N>

where Offset<OFF, N>: TokenParse,

fn parse(parser: &mut Parser) -> Result<Self, ParseErr>

Attempt to convert the next sequence of tokens in the parser’s state into a component.

impl<OFF: PartialEq, const N: u32> PartialEq for PCOffset<OFF, N>

fn eq(&self, other: &PCOffset<OFF, N>) -> 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.
