Struct Wag 

pub struct Wag {
    pub metadata: SpannableNode<Metadata>,
    pub grammar: Vec<SpannableNode<Rule>>,
}

The full WAG tree.

Grammar

Wag -> Metadata? Rule*;

Fields

metadata: SpannableNode<Metadata>

Metadata associated with this WAG.

grammar: Vec<SpannableNode<Rule>>

The actual grammar.

Implementations

impl Wag

pub fn new_unspanned(metadata: Metadata, grammar: Vec<Rule>) -> Self

Constructs a Self with dummy span information.

Trait Implementations

impl Debug for Wag

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

Formats the value using the given formatter.

impl Display for Wag

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

Formats the value using the given formatter.

impl Hash for Wag

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 Wag

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 Wag

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