pub struct ExprNode {
    pub items: Vec<AstNodeId>,
    pub span: SourceSpan,
}

In XPath, (a, b, c) creates a sequence containing results of a, b, and c.

Fields

items: Vec<AstNodeId>

List of expression IDs in the sequence.

span: SourceSpan

pub fn sequence(items: Vec<AstNodeId>, span: SourceSpan) -> Self

Create a sequence with multiple expressions.

pub fn append(&mut self, id: AstNodeId, end: usize)
