Enum ASTValue

pub enum ASTValue {
    TokenValue(Token),
    Unary(UnaryNode),
    Binary(BinaryNode),
    List(Vec<ASTValue>),
    Mapping(Vec<(Token, ASTValue)>),
    Slice(Location, Box<Option<ASTValue>>, Box<Option<ASTValue>>, Box<Option<ASTValue>>),
}

This represents AST nodes corresponding to fragments of CFG source.

Variants

TokenValue(Token)

This is a token in the CFG grammar.

Unary(UnaryNode)

This is a unary node.

Binary(BinaryNode)

This is a binary node.

List(Vec<ASTValue>)

This is a list node.

Mapping(Vec<(Token, ASTValue)>)

This is a mapping node.

Slice(Location, Box<Option<ASTValue>>, Box<Option<ASTValue>>, Box<Option<ASTValue>>)

This is a slice node. It’s produced when parsing slices.

Trait Implementations

impl Clone for ASTValue

fn clone(&self) -> ASTValue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ASTValue

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

Formats the value using the given formatter.

impl Display for ASTValue

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

Formats the value using the given formatter.

impl PartialEq for ASTValue

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