Struct RenderCounts 

#[non_exhaustive]
pub struct RenderCounts {
    pub nodes: usize,
    pub bytes: usize,
    pub list_iterations: usize,
    pub walk_time: Duration,
}

What one render did, for the application’s own logs and metrics.

On a crate::RenderError for a budget or a fault, the same counts say how far the walk got. For a page served without a walk (a browser shell, or the deprecated render_page’s fallback) every count is zero. nodes and list_iterations are counted by crate::try_render; a page from the deprecated render_page reports them as zero.

The walk time is the number to watch for moving a page off an async worker: see crate::try_render’s spawn_blocking recipe.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

nodes: usize

Elements and text nodes the walk wrote (hydration markers and comments are not nodes).

bytes: usize

Bytes of HTML the walk wrote into the page’s root, the quantity the walker’s output budget (WalkLimits::max_output_bytes) bounds; the document around it is not counted.

list_iterations: usize

List rows the walk wrote, across every nesting depth, the quantity WalkLimits::max_list_iterations bounds.

walk_time: Duration

Time spent in the walk.
