wr_perf_handlers

Purpose

Registration surface for performance self-check handlers. WR’s self-check iterates over all registered handlers and packages their reports into one artefact. Child plugins own performance-relevant code paths; this filter lets them expose those paths to the self-check without direct coupling.

There are two equivalent registration paths — use whichever fits your plugin:

• Programmatic: PerfHandlers::register( 'yourplugin_form_perf', $callable )
• WordPress filter: return your handlers from wr_perf_handlers

Usage

add_filter( 'wr_perf_handlers', function ( array $handlers ): array {
    $handlers['yourplugin_form_perf'] = static function (): PerfHandlerReport {
        // measure your hot path and return a report
    };
    return $handlers;
} );

Parameters

• $handlers (array<string, callable>): Map of handler id → callable returning a PerfHandlerReport. Add your handlers and return the array.
