//! Sample `lazy_static` function which provides an utility

//! A simple utility to count the number of allocated objects per type:
//! declared a field of type `ObjectCounter<T>` inside your type `T`,
//! and then `ObjectCounter::<T>::count()` will return the number of
//! allocated objects.
//!
//! This could be used for example a quick and dirty way to count
//! domain-specific objects e. g. sockets, connections, buffers,
//! requests etc.

The problem

Idris termination detection on values to be structurally smaller when calling function recursively. For example in this case the compiler understands that xs is smaller than x :: xs:

foo : List a -> ()
foo (x :: xs) = foo xs
foo [] = ()

I recall a dream from childhood
Wave of magic delight (it is actually some gibberish)
Ded Moroz (Russian version of Santa Claus) will come to me
And will bring his bag

Childhood went into fog
Youth went far away
But at Chistmas night
I see the tale again and again

Obsidian is a note-taking app

Obsidian is a gem.

It is the app I always wanted.

A long time ago I used Evernote

Evernote was great, but it degraded over time: they had a nice and fast note-taking app and added hundreds of functions I don't need. It became slow and the interface became overloaded in the last version I used many years ago.

        let i = futures::executor::block_on(tokio::task::unconstrained(fut)).unwrap();
