Variants

Rc(Rc<Element<'el, L>>)

A refcounted member.

Borrowed(&'el Element<'el, L>)

A borrowed element.

Literal(Cons<'el>)

A borrowed string.

Quoted(Cons<'el>)

A borrowed quoted string.

LangBox(LangBox<'el, L>)

Language-specific boxed items.

Registered(LangBox<'el, L>)

A custom element that is not rendered.

PushSpacing

Push a new line, unless the current line is empty.

Line

Unconditionally push a line.

Spacing

Spacing between language items.

LineSpacing

Push a new line, unless the current line is empty, then add another line after that to create an empty line as spacing.

Indent one step.

Unindent

Unindent one step.

None

Empty element which renders nothing.
