tuple_storage

Store one kind of tuple per file with ease. Every access is type-safe.

The database is memory mapped for fast access even as the set grows.

Example usage

```bash $ cargo run create target/demo.ts '(u8, i16, u32, i64)' $ cargo run show target/demo.ts (u8, i16, u32, i64)

$ cargo run insert target/demo.ts '(1, 2, 3, 4)' $ cargo run insert target/demo.ts '(6, 7, 8, 9)' $ cargo run insert target/demo.ts '(3, 4, 5, 6)'

$ cargo run search target/demo.ts [ (1, 2, 3, 4) (3, 4, 5, 6) (6, 7, 8, 9) ] found 3 Tuples

$ cargo run search target/demo.ts '<3' [ (1, 2, 3, 4) ] found 1 Tuples $ cargo run search target/demo.ts '=3' [ (3, 4, 5, 6) ] found 1 Tuples $ cargo run search target/demo.ts '>3' [ (6, 7, 8, 9) ] found 1 Tuples

$ cargo run remove target/demo.ts '>3' removed 1 Tuples $ cargo run search target/demo.ts '>3' [] found 0 Tuples

inserting Tuple violating the Schema:

$ cargo run insert target/demo.ts '(-23, 0, 0, 0)' thread 'main' panicked at 'called Result::unwrap() on an Err value: ParseIntError { kind: InvalidDigit }', libcore/result.rs:945:5 note: Run with RUST_BACKTRACE=1 for a backtrace.

searching with an invalid search index

$ cargo run search target/demo.ts '=-2' thread 'main' panicked at 'called Result::unwrap() on an Err value: ParseIntError { kind: InvalidDigit }', libcore/result.rs:945:5 note: Run with RUST_BACKTRACE=1 for a backtrace. ```
