Enum LimitExceeded 

#[non_exhaustive]
pub enum LimitExceeded {
    RenderPixels {
        width: u32,
        height: u32,
        allowed: u64,
    },
    Time {
        budget: Duration,
        during: Operation,
        page: Option<PageIndex>,
    },
    Stopped {
        during: Operation,
        page: Option<PageIndex>,
    },
}

A caller-set ceiling was hit. The error a render or an open answers when a Limits field that defaults to off was set and exceeded.

Distinct from the parser’s own caps, which are damage tolerance and answer with a diagnostic or a truncated value: these are the host’s, and the host asked to be told. The message names the cap and what would satisfy it.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

RenderPixels

A render target of width × height pixels has more than Limits::max_render_pixels allows.

Fields

width: u32

The target’s width in pixels.

height: u32

The target’s height in pixels.

allowed: u64

The cap, in pixels.

Time

Limits::deadline passed while during was under way.

Fields

budget: Duration

How much time was allowed.

during: Operation

What was being done.

page: Option<PageIndex>

The page it was being done to, where the caller knew one.

Stopped

Limits::deadline was raised by Deadline::stop while during was under way.

Fields

during: Operation

What was being done.

page: Option<PageIndex>

The page it was being done to, where the caller knew one.

Implementations

impl LimitExceeded

pub fn on_page(self, page: PageIndex) -> LimitExceeded

The same error naming page, for the caller who knows which page the engine below it was working on. Only LimitExceeded::Time has a page; the pixel cap already names its size.
