Crate murmur_wasm 

Murmur WASM - WebAssembly probe runtime.

This crate provides browser-side probes that can measure network timing from within a web page. It uses the Fetch API and Performance APIs to capture timing data.

Capabilities

In WASM, we can:

• Make HTTP/HTTPS requests via Fetch API
• Measure request timing (DNS, TCP, TLS, TTFB)
• Access Navigation Timing and Resource Timing APIs
• Read network connection information

We cannot:

• Make raw TCP/UDP connections
• Send ICMP packets (ping/traceroute)
• Access low-level network interfaces

Usage

import init, { probe_url, get_timing } from 'murmur-wasm';

await init();
const result = await probe_url('https://example.com');
console.log(result);

Structs

WasmConnectionInfo

Network connection information.

WasmNavigationTiming

WasmResourceTiming

Resource timing entry.

Functions

get_navigation_timing

Get navigation timing data for the current page.

get_resource_timings

Get all resource timing entries.

log

Console log helper for debugging.

probe_url
