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

Variants

TzCount

TZCOUNT(value)

Int(u32)

32-bit literal.

Sym(u32)

Implementations

impl RpnOp<'_>

pub fn arity(&self) -> Arity

The operation’s arity.

pub fn precedence(&self) -> u8

The operation’s precedence.

Panics

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

pub fn is_associative(&self) -> bool

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

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

Trait Implementations

impl<'a> Debug for RpnOp<'a>

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

Formats the value using the given formatter.

impl Display for RpnOp<'_>

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

Formats the value using the given formatter.

impl<'a> PartialEq for RpnOp<'a>

fn eq(&self, other: &RpnOp<'a>) -> 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.
