Locksmith

This crate provides the logic for detecting the impact of a given SQL statement on a Postgres database.

It is the brains behind locksmith-cli.

Detecting the impact of a statement

use locksmith::QueryOracle;

async fn inspect_statement() {
    let mut oracle = QueryOracle::new("postgres://localhost:5432/mydb");
    let inspection = oracle.inspect_statement("alter table customers alter column id type bigint;").await.unwrap();
    println!("{:?}", inspection.locks);
}
