}

A RPN operation; since this means “operation on the RPN stack” here, this includes literals, not just operators.

Variants

Add

+ operator.

Sub

- operator.

Mul

* operator.

Div

/ operator.

Mod

% operator.

Neg

Unary - operator.

Pow

** operator.

BinOr

| operator.

BinAnd

& operator.

Xor

^ operator.

Cpl

~ operator.

And

&& operator.

Or

|| operator.

Not

! operator.

Eq

== operator.

Neq

!= operator.

Gt

> operator.

Lt

< operator.

Gte

>= operator.

Lte

<= operator.

Lsh

<< operator.

Rsh

>> operator.

BankSym(u32)

BANK(Symbol)

BankSect(&'a [u8])

BANK("section")

BankSelf

BANK(@)

SizeofSect(&'a [u8])

SIZEOF("section")

StartofSect(&'a [u8])

STARTOF("section")

HramCheck

HRAM check (check if the value is in HRAM range, then & 0xFF).

RstCheck

rst check (check if the value is a rst target, then | 0xC7).

Int(u32)

32-bit literal.

Sym(u32)

Symbol (referenced by 32-bit ID).

Implementations

impl RpnOp<'_>[src]

pub fn arity(&self) -> Arity[src]

The operation’s arity.

pub fn precedence(&self) -> u8[src]

The operation’s precedence.

Panics

This function panics if the operation is not a binary operator.

pub fn is_associative(&self) -> bool[src]

Whether this operation is associative; that is, if A op (B op C) == (A op B) op C.

Panics

This function panics if the operation is not a binary operator.

pub fn needs_parens(&self, parent: &RpnOp<'_>, is_left: bool) -> bool[src]

Computes whether parens are needed (for pretty-printing) around a child expression, with the given parent.
