//! The text content type.
//!
//! **Text** contains phrasing content such as
//! [attention][crate::construct::attention] (emphasis, strong),
//! [code (text)][crate::construct::code_text], and actual text.
//!
//! The constructs found in text are:
//!
//! * [Attention][crate::construct::attention]
//! * [Autolink][crate::construct::autolink]
//! * [Character escape][crate::construct::character_escape]
//! * [Character reference][crate::construct::character_reference]
//! * [Code (text)][crate::construct::code_text]
//! * [Hard break (escape)][crate::construct::hard_break_escape]
//! * [HTML (text)][crate::construct::html_text]
//! * [Label start (image)][crate::construct::label_start_image]
//! * [Label start (link)][crate::construct::label_start_link]
//! * [Label end][crate::construct::label_end]
//!
//! > 👉 **Note**: for performance reasons, hard break (trailing) is formed by
//! > [whitespace][crate::construct::partial_whitespace].
