pub fn text_expr(value: &str) -> Result<String, String>Expand description
The Rust expression for a text attribute, its @ forms as everywhere
in Yog Data (yog_data::typed): "@Strings.title" is a text of
resources/Strings.yres (see set_resource_refs), "@lang:gui.done"
any translation key, "@item:minecraft:stick" (@block:, @entity:)
that content’s name — each looked up when the tree is built
(::yog_api::tr, so it follows the game’s language); "@@..." is a
literal text starting with @; anything else is the literal text.
