# sdb
a user-friendly wrapper for [sanakirja](https://docs.rs/sanakirja/latest/sanakirja/) database
sanakirja a key can have multiple values , this is different from the other k-v databases .
## about
sanakirja author is [Pierre-Étienne Meunier](https://twitter.com/pijul_org) .
see [Sanakirja 1.0 (pure Rust transactional on-disk key-value store) released!](https://www.reddit.com/r/rust/comments/lp5jez/sanakirja_10_pure_rust_transactional_ondisk/)
> Sanakirja is at least 10 times faster than Sled in my (sequential) benchmarks, and even 20%-50% faster than LMDB (the fastest C equivalent) in the same benchmarks. Also, I started it when there was no real alternative (Sled didn't exist at the time).
[I](https://github.com/rmw-link/sdb) wrapper it for easy use .
First step : static define db , see [tests/db.rs](./tests/db.rs)
I use `static_init = {git="https://gitlab.com/vkahl/static_init.git"}` for static init ( use git version because of [bug](https://gitlab.com/okannen/static_init/-/issues/7) ) . You can use [lazy_static](https://docs.rs/crate/lazy_static) instead .
```rust
#include ./tests/db.rs
```
Second step : use it , see [tests/main.rs](./tests/main.rs)
```rust
#include ./tests/main.rs
```
db method you can see [src/dbpage.rs](./src/dbpage.rs)
```rust
#include ./src/dbpage.rs
```
