Struct wagon_parser::parser::comp::Comparison

pub struct Comparison {
    pub sum: SpannableNode<Sum>,
    pub comp: Option<Comp>,
}

A comparison between two Sums.

If comp == None, then this is just a Sum.

Grammar

Comparison -> [Sum] ([CompOp] [Sum])?;

Fields

sum: SpannableNode<Sum>

The left-hand side of the comparison

comp: Option<Comp>

The optional operator and right-hand side.

Implementations

impl Comparison

pub fn new_unspanned(sum: Sum, comp: Option<Comp>) -> Self

Constructs a Self with dummy span information.

Trait Implementations

impl Clone for Comparison

fn clone(&self) -> Comparison

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Comparison

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

Formats the value using the given formatter.

impl Display for Comparison

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

Formats the value using the given formatter.

impl Hash for Comparison

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 Comparison

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

where Self: Sized,

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 Comparison

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