Struct rsvg::text::Chars

source ·
pub struct Chars {
    string: RefCell<String>,
    space_normalized: RefCell<Option<String>>,
}
Expand description

In SVG text elements, we use Chars to store character data. For example, an element like <text>Foo Bar</text> will be a Text with a single child, and the child will be a Chars with “Foo Bar” for its contents.

Text elements can contain <tspan> sub-elements. In this case, those tspan nodes will also contain Chars children.

A text or tspan element can contain more than one Chars child, for example, if there is an XML comment that splits the character contents in two:

<text>
  This sentence will create a Chars.
  <!-- this comment is ignored -->
  This sentence will cretea another Chars.
</text>

When rendering a text element, it will take care of concatenating the strings in its Chars children as appropriate, depending on the xml:space="preserve" attribute. A Chars stores the characters verbatim as they come out of the XML parser, after ensuring that they are valid UTF-8.
