fun-htmx 1.1.0

#![cfg_attr(not(feature = "std"), no_std)]
#![cfg_attr(docsrs, feature(doc_auto_cfg))]
#![warn(missing_docs)]

//! This crate provides a collection of [HTMX](https://htmx.org) attributes for [`fun-html`](https://github.com/jcornaz/fun-html/)
//!
//! # Example
//!
//! ```
//! use fun_html::{elt::{script_empty, button, text}, attr::src};
//! use fun_htmx::{hx_get, hx_swap_outer_html};
//!
//! let quick_start = [
//!    script_empty([src("https://unpkg.com/htmx.org@2.0.3")]),
//!    button(
//!      [hx_get("/clicked"), hx_swap_outer_html()],
//!      text("Click Me")
//!    ),
//! ];
//! ```
//! ## Feature flags
//!
//! * `std`: enabled by default. must be disabled to compile to `no_std`
//! * `serde_json`: Add utilities like `hx_vals_serde(values: &impl Serialize)` that relies on `serde` serialization to output json
//!
