Struct Ast 

pub struct Ast {
    pub root: SourceFile,
    pub source_map: SourceMap,
    pub body_statements: Vec<Vec<AstStatement>>,
}

The typed abstract syntax tree.

This is a semantic projection — it is NOT required to preserve whitespace, comments, or exact delimiter positions. Pretty-printing from the AST produces equivalent but not byte-identical output.

Fields

root: SourceFile

The root source-file node.

source_map: SourceMap

Source map for AST nodes (maps node IDs to spans).

body_statements: Vec<Vec<AstStatement>>

Body statements for each top-level declaration, in parallel with root.declarations. body_statements[i] is the lowered body of root.declarations[i]. Declarations with no body (e.g., package specs, views, DDL) carry an empty inner vec. Defaulting to empty so existing callers that produce an Ast without body lowering remain valid (backward-compatible; R13).

Implementations

impl Ast

pub fn new() -> Self
