Struct StretchElem

pub struct StretchElem {
    pub body: Content,
    /* private fields */
}

Stretches a glyph.

This function can also be used to automatically stretch the base of an attachment, so that it fits the top and bottom attachments.

Note that only some glyphs can be stretched, and which ones can depend on the math font being used. However, most math fonts are the same in this regard.

$ f : X stretch(->>, size: #150%)_"surjective" Y $
$ x stretch(harpoons.ltrb, size: #3em) y

fn has(&self, id: u8) -> bool

Whether the element has the given field set.

fn field(&self, id: u8) -> Result<Value, FieldAccessError>

Get the field with the given field ID.
