This change will attempt to load an .env file from CARGO_MANIFEST_DIR, if it exists.
For backwards compatibility, if the .env file does not exist, we will fall back to default dotenv behaviour.
Resolves#267
Before, the query would be formatted equivalent to the input string:
```
[2020-04-18T23:47:32Z DEBUG sqlx_core::postgres::executor] SELECT id, queue, ..., elapsed: 2.320µs
SELECT id, queue, payload, status, priority, created_at, updated_at
FROM jobs
WHERE status = $1
ORDER BY priority ASC, created_at ASC
```
After, the query is formatted cleanly and consistently:
```
[2020-04-19T00:30:18Z DEBUG sqlx_core::postgres::executor] SELECT id, queue, ..., elapsed: 2.280µs
SELECT
id,
queue,
payload,
status,
priority,
created_at,
updated_at
FROM
jobs
WHERE
status = $1
ORDER BY
priority ASC,
created_at ASC
```
This uses the `sqlformat` crate, which was ported from the
Javascript `sql-formatter-plus` library specifically for this purpose.
Since the implementation of Encode and Decode for both mysql and
postgres on serde's Value and RawValue were practically the same they
were moved to the generic json module.
Prints each query performed at DEBUG level,
along with a timing of how long the query took
to execute.
Slow queries will be printed at WARN level.
Currently the slow query threshold is
hardcoded to 1 second.
