Struct LineNode

pub struct LineNode<'a> {
    pub pair: Pair<'a, Rule>,
    pub line_no: i64,
    pub children: Vec<LineNode<'a>>,
}

Represents a line in the Plan tree structure before it’s converted to a relation. This allows us to build the tree structure first, then convert to relations with proper parent-child relationships.

Fields

pair: Pair<'a, Rule>

line_no: i64

children: Vec<LineNode<'a>>

Implementations

impl<'a> LineNode<'a>

pub fn context(&self) -> ParseContext

pub fn parse(line: &'a str, line_no: i64) -> Result<Self, ParseError>

pub fn parse_root(line: &'a str, line_no: i64) -> Result<Self, ParseError>

Parse the root relation of a plan, at depth 0.

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

Performs copy-assignment from source.

impl<'a> Debug for LineNode<'a>

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