Adding `t4` library as a dependency

Run this command in a terminal, in your project's directory:

cargo add t4

To add it manually, edit your project's Cargo.toml file and add to the [dependencies] section:

t4 = "0.1.7"

The t4 library will be automatically available globally. Read the t4 library documentation.

Readme

`t4`

t4 is a local, embedded, high-performance object store.

Features

Performance, correctness, and ergonomics, pick three.
io_uring for all I/O, scale to modern SSDs.
Deterministic, predictable performance, one request is one I/O.
Runtime-agnostic async API.

Usage

Values are written and read by key. Reads support full-value and range access.

let store = t4::mount("your-data.t4").await?;

store.put(b"a.txt", b"Hello, world!").await?;

let content = store.get(b"a.txt").await?;
assert_eq!(content, b"Hello, world!");

let slice = store.get_range(b"a.txt", 7, 5).await?;
assert_eq!(slice, b"world");

let removed = store.remove(b"a.txt").await?;
assert!(removed);

Limitations

File name is up to 256 bytes, file size is up to 4 GB.

Vision

t4 will be the ultimate and only file system you need.
