//! A library for communicating with a libSQL database over HTTP.
//!
//! libsql-client is a lightweight HTTP-based driver for sqld,
//! which is a server mode for libSQL, which is an open-contribution fork of SQLite.
//!
//! libsql-client compiles to wasm32-unknown-unknown target, which makes it a great
//! driver for environments that run on WebAssembly.
//!
//! It is expected to become a general-purpose driver for communicating with sqld/libSQL,
//! but the only backend implemented at the moment is for Cloudflare Workers environment.
