Struct lc3_ensemble::ast::Reg

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

A register. Must be between 0 and 7.

This Reg struct can either be constructed by selecting a register from reg_consts, or by using Reg::try_from.

Examples

AND R0, R0, #0
    ~~  ~~    
ADD R1, R1, R0
    ~~  ~~  ~~
LD R2, VALUE
   ~~         
NOT R1, R2
    ~~  ~~    

Implementations

impl Reg

pub fn reg_no(self) -> u8

Gets the register number of this Reg. This is always between 0 and 7.

Trait Implementations

impl Clone for Reg

fn clone(&self) -> Reg

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Reg

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

Formats the value using the given formatter.

impl Display for Reg

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

Formats the value using the given formatter.

impl From<Reg> for usize

fn from(value: Reg) -> Self

Converts to this type from the input type.

impl Hash for Reg

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 Index<Reg> for RegFile

type Output = Word

The returned type after indexing.

fn index(&self, index: Reg) -> &Self::Output

Performs the indexing (container[index]) operation.

impl IndexMut<Reg> for RegFile

fn index_mut(&mut self, index: Reg) -> &mut Self::Output

Performs the mutable indexing (container[index]) operation.

impl PartialEq for Reg

fn eq(&self, other: &Reg) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl TokenParse for Reg

type Intermediate = Reg

An intermediate to hold the match before it is converted to the actual component.

fn match_(m_token: Option<&Token>, span: Span) -> Result<Self, ParseErr>

Tries to match the next token to the given component, if possible.

fn convert(imed: Self::Intermediate, _span: Span) -> Result<Self, ParseErr>

Parses the intermediate into the given component, raising an error if conversion fails.

impl TryFrom<u8> for Reg

type Error = TryFromIntError

The type returned in the event of a conversion error.

fn try_from(value: u8) -> Result<Self, Self::Error>

Performs the conversion.

impl Copy for Reg

impl Eq for Reg

impl StructuralPartialEq for Reg
