//! The `content`, ahum, content type.
//!
//! **Content** is zero or more definitions, and then zero or one paragraph.
//! It’s a weird one, and needed to make certain edge cases around definitions
//! spec compliant.
//! Definitions are unlike other things in markdown, in that they behave like
//! **text** in that they can contain arbitrary line endings, but *have* to end
//! at a line ending.
//! If they end in something else, the whole definition instead is seen as a
//! paragraph.
//!
//! The constructs found in content are:
//!
//! * Definition
//! * Paragraph
use crate::tokenizer::{Code, State, StateFnResult, TokenType, Tokenizer};
/// Before content.
///
/// ```markdown
/// |[x]: y
/// |asd
/// ```

// _ => tokenizer.attempt(definition, |ok| {
// Box::new(if ok {
// a
