Struct wagon_parser::parser::chunk::Chunk

pub struct Chunk {
    pub chunk: ChunkP,
    pub ebnf: Option<EbnfType>,
}

A chunk of an Rhs.

Chunks are symbols in () with optionally an EBNF token following it. If there are no (), there is only 1 symbol, which may still optionally have an EBNF token.

Grammar

Chunk -> ChunkP EbnfType?;

Fields

chunk: ChunkP

The actual chunk part.

ebnf: Option<EbnfType>

The possible EBNF operator.

Implementations

impl Chunk

pub fn new_unspanned(chunk: ChunkP, ebnf: Option<EbnfType>) -> Self

Constructs a Self with dummy span information.

impl Chunk

pub fn simple_terminal(term: &str) -> Self

Check if this chunk is a terminal Automatically create a Chunk that is just a terminal. See Symbol::simple_terminal.

pub fn simple_ident(ident: &str) -> Self

Automatically create a Chunk that is just an ident. See Symbol::simple_ident.

pub fn empty() -> Self

Automatically create an empty chunk.

pub fn extract_symbols(self) -> Vec<SpannableNode<Symbol>>

Extract all the symbols that are in this chunk.

Trait Implementations

impl Clone for Chunk

fn clone(&self) -> Chunk

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Chunk

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

Formats the value using the given formatter.

impl Display for Chunk

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

Formats the value using the given formatter.

impl Hash for Chunk

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 Chunk

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 Chunk

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