Enum Factor 

pub enum Factor {
    Primary(SpannableNode<Atom>),
    Power {
        left: SpannableNode<Atom>,
        right: Box<SpannableNode<Factor>>,
    },
}

A possible power equation, or just an Atom.

Grammar

Factor -> Atom (“**” Factor)?;

Variants

Primary(SpannableNode<Atom>)

Just an Atom.

Power

A power equation

Fields

left: SpannableNode<Atom>

The left-hand side.

right: Box<SpannableNode<Factor>>

Whatever to evaluate to the power to.

Implementations

impl Factor

pub fn new_unspanned_primary(arg_0: Atom) -> Self

Construct a Self::Primary with dummy span information.

Trait Implementations

impl Clone for Factor

fn clone(&self) -> Factor

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Factor

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

Formats the value using the given formatter.

impl Display for Factor

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

Formats the value using the given formatter.

impl Hash for Factor

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 Parse for Factor

fn parse(lexer: &mut LexerBridge<'_>) -> ParseResult<Self>

Given a lexer, try to parse a valid instance of this node.

fn parse_sep( lexer: &mut LexerBridge<'_>, join: Tokens, ) -> ParseResult<Vec<Self>>

where Self: Sized,

Parse multiple instances of this node, separated by a Tokens.

fn parse_sep_end( lexer: &mut LexerBridge<'_>, join: Tokens, end: Tokens, ) -> ParseResult<Vec<Self>>

where Self: Sized,

Parse multiple instances of this node, separated by a Tokens end ended by a (possibly different) Tokens.

impl PartialEq for Factor

fn eq(&self, other: &Factor) -> 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.
