Struct AddExpressionNode 

pub struct AddExpressionNode {
    pub parent: Option<NodeId>,
    pub children: Vec<NodeId>,
    pub operators: Vec<AddOp>,
    pub begin_token: TokenId,
    pub end_token: TokenId,
}

AST node for addExpression production

Fields

parent: Option<NodeId>

Parent node (if any)

children: Vec<NodeId>

Child nodes

operators: Vec<AddOp>

Operators between children: operators[i] is between children[i] and children[i+1]

begin_token: TokenId

First token of this node

end_token: TokenId

Last token of this node

Implementations

impl AddExpressionNode

pub fn new(begin_token: TokenId, end_token: TokenId) -> Self
