#![deny(missing_docs)]

//! Helper for [`minidom`] to write XML.
//!
//! ## Description
//! The crate provides [`ElementWriter`] which can write an [`Element`].
//!
//! ## Example
//!
//! ```
//! use minidom::{Element, Node};
//! use minidom_writer::ElementWriter;
//! use std::io::Cursor;
//!
//! let subtag = Element::builder("ns:subtag")
//!     .attr("id", "my_subtag")
//!     .append(Node::Text(String::from("Some text")))
//!     .build();
//! let tag = Element::builder("tag")
//!     .attr("id", "my_tag")
//!     .append(subtag)
//!     .build();
//! let write = Cursor::new(Vec::new());
//! let mut element_writer = ElementWriter::plain(write);
//! element_writer.write(&tag).unwrap();
//! let expected = r#"<?xml version="1.0" encoding="UTF-8"?><tag id="my_tag"><ns:subtag id="my_subtag">Some text</ns:subtag></tag>"#;
//! assert_eq!(expected, String::from_utf8(element_writer.into_inner().into_inner()).unwrap());
//! ```
//!

//! [`ElementWriter`]: struct.ElementWriter.html
