TraceProcessor RPC

This directory contains the RPC interfaces to use the Perfetto Trace Processor remotely (i.e. not just in-process). It consists of two targets:

wasm_bridge

The WASM (Web Assembly) interop bridge. It's used to call the Trace Processor from HTML/JS using WASM's ccall.

httpd

The HTTP RPC module. It exposes a protobuf-over-HTTP RPC interface that allows interacting with a remote trace processor instance. It's used for special UI use cases (very large traces > 2GB) and for python interoperability.
