//! Internal library for the `math-core` crate for rendering MathML.
//!
//! This library allows you to construct an AST representing MathML and then render it to a string.
//!
//! # Example
//!
//! ```rust
//! use math_core_renderer_internal::ast::Node;
//! use math_core_renderer_internal::symbol;
//! use math_core_renderer_internal::attribute::{MathSpacing, LetterAttr, OpAttrs};
//!
//! let ast = Node::Row {
//! nodes: &[
//! &Node::Under {
//! target: &Node::Operator {
//! op: symbol::N_ARY_SUMMATION.as_op(),
//! attrs: OpAttrs::empty(),
//! left: Some(MathSpacing::Zero),
//! right: None,
//! size: None,
//! },
//! symbol: &Node::IdentifierChar('i', LetterAttr::Default),
//! },
//! &Node::IdentifierChar('i', LetterAttr::Default),
//! ],
//! attr: None,
//! };
//!
//! let mut output = String::new();
//! ast.emit(&mut output, 0).unwrap();
//! assert_eq!(
//! output,
//! "<mrow><munder><mo lspace=\"0\">∑</mo><mi>i</mi></munder><mi>i</mi></mrow>"
//! );
//! ```
