Struct Diagnostics 

pub struct Diagnostics {
    pub error: Option<String>,
    pub stale: bool,
    pub warnings: Vec<Warning>,
}

What is wrong with the document right now, the model behind the dev overlay.

An error means the file could not be loaded at all: there is no tree to show, so the window would otherwise be blank (or, on hot-reload, silently stale). A warning means the document built, but something in it does nothing, an unhonored property, an unknown pseudo-class, an undefined var(), an unsupported @media.

Both used to go only to stderr, which nobody running a GUI app is watching.

Fields

error: Option<String>

The load/parse failure, if the document is currently broken.

stale: bool

Whether the tree on screen predates that error (a failed hot-reload keeps the last good UI rather than blanking the window).

warnings: Vec<Warning>
