Just a small gist to show how you can easily create a Rust shared lib, wrap it with C and call it from PostgreSQL SQL Command.

Prereq : Tested on Ubuntu 18, GCC, postgresql-server-11, postgresql-dev-11, rustlang
Create new project Cargo embed and cd embed
Rename the file src/main.rs to lib.rs
Add following code

#[no_mangle]
pub extern fn double_input(input: i32) -> i32 {
    input * 2

Results of Skia's nanobench for each of available configs.

The RPi4 board was using default clocks and was provided adequate power and cooling. The tests were conducted on fully-updated Raspbian Buster.

I'd love to test with RPi3B and RPi3B+ that I have, but my charger and PSU seem to be too weak, as both boards report "under voltage" condition.

	--------------------------- MODULE MemoryTracking ---------------------------
	(* A memory allocator which tracks usage by "phase" *)

	CONSTANTS Phase, (* A set of phases *)
	Thread, (* A set of threads *)
	Address (* A set of addresses *)

	VARIABLES memory, (* All in-use allocations *)
	memoryByPhase, (* A mapping from phases to sets of allocated items *)
	memoryByThread (* A mapping from threads to an allocated record *)

	If you've got something like this:

	file was built for arm64 which is not the architecture being linked (x86_64):

	Than this gist is for you.

	Let's say you have already developed the framework itself and just want to build the binary
	and distribute it through the Cocoapods.

	1. Make sure your framework "Deployment Target" is equal to all the dependencies from your podspec file.
