--- This experimental rust extension allows reading ClickHouse Native files with DuckDB
--- Test files can be generated with clickhouse-local. See README for full examples.

--- Simple Example
D SELECT * FROM clickhouse_native('/tmp/numbers.clickhouse');
┌──────────────┬─────────┐
│ version() │ number │
│ varchar │ int32 │
├──────────────┼─────────┤
│ 24.12.1.1273 │ 0 │
└──────────────┴─────────┘

--- Long Example
D SELECT count(*), max(number) FROM clickhouse_native('/tmp/100000.clickhouse');
┌──────────────┬─────────────┐
│ count_star() │ max(number) │
│ int64 │ int32 │
├──────────────┼─────────────┤
│ 100000 │ 99999 │
└──────────────┴─────────────┘

--- Wide Example
D SELECT * FROM clickhouse_native('/tmp/functions.clickhouse') WHERE alias_to != '' LIMIT 10;
┌────────────────────┬──────────────┬──────────────────┬──────────────────────┬──────────────┬─────────┬───┬─────────┬───────────┬────────────────┬──────────┬────────────┐
