pub fn parse(input: &str) -> Result<Statement, ParseError>

Parse a PowQL query string into an AST Statement.

Examples

use powdb_query::parser::parse;
use powdb_query::ast::Statement;

// A bare type name is a query (select all rows).
let stmt = parse("User").unwrap();
assert!(matches!(stmt, Statement::Query(_)));

use powdb_query::parser::parse;
use powdb_query::ast::Statement;

// DDL: define a new type (table).
let stmt = parse("type User { required name: str, age: int }").unwrap();
assert!(matches!(stmt, Statement::CreateType(_)));
