Crate yehorbolt_sql_parser

SQL parser

This is a simple SQL parser written in Rust using the pest library. The parser supports parsing CREATE TABLE statements with column definitions.

Example

extern crate yehorbolt_sql_parser;
use yehorbolt_sql_parser::parse_sql;

fn main() {
   let table = "CREATE TABLE financial_report
   {
       id INT,
       currency_name TEXT,
       is_usable BOOL
   }";
   let res = parse_sql(table);
   println!("Parsed: {:#?}", res);
}

In this example, the parse_sql function is used to parse the provided SQL CREATE TABLE statement, and the parsed result is printed using println! (with {:?}).
