Enum Atom 

pub(crate) enum Atom {
    SymbolOrLiteral(SymbolOrLiteral),
    Parens(SimpleSpan, Script, Box<ArithmeticExpression>),
    RcRef(SimpleSpan, RegistersContaining),
}

A component of an arithmetic expression.

A symbol, numeric literal, address of an RC-word, or a parenthesised arithmetic expression.

Variants

SymbolOrLiteral(SymbolOrLiteral)

Parens(SimpleSpan, Script, Box<ArithmeticExpression>)

RcRef(SimpleSpan, RegistersContaining)

Implementations

Trait Implementations

impl Clone for Atom

fn clone(&self) -> Atom

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Atom

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

Formats the value using the given formatter.

impl Display for Atom

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

Formats the value using the given formatter.

impl Evaluate for Atom

fn evaluate<R: RcUpdater>( &self, ctx: &mut EvaluationContext<'_, R>, scope: ScopeIdentifier, ) -> Result<Unsigned36Bit, EvaluationFailure>

impl From<(SimpleSpan, Script, SymbolName)> for Atom

fn from((span, script, name): (SimpleSpan, Script, SymbolName)) -> Self

Converts to this type from the input type.

impl From<(SimpleSpan, Script, Unsigned36Bit)> for Atom

fn from((span, script, v): (SimpleSpan, Script, Unsigned36Bit)) -> Atom

Converts to this type from the input type.

impl From<Atom> for ArithmeticExpression

fn from(a: Atom) -> ArithmeticExpression

Converts to this type from the input type.

impl From<Atom> for SignedAtom

fn from(magnitude: Atom) -> Self

Converts to this type from the input type.

impl From<LiteralValue> for Atom

fn from(literal: LiteralValue) -> Atom

Converts to this type from the input type.

impl From<SymbolOrLiteral> for Atom

fn from(value: SymbolOrLiteral) -> Self

Converts to this type from the input type.

impl PartialEq for Atom

fn eq(&self, other: &Atom) -> 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 Spanned for Atom

fn span(&self) -> SimpleSpan

impl Eq for Atom

impl StructuralPartialEq for Atom
