How to build SQLite3 .lib file on Windows 10

1. Download source from source (https://www.sqlite.org/download.html)

   For example: source https://www.sqlite.org/2020/sqlite-amalgamation-3310100.zip

2. Download binary from binary

   For example: binary https://www.sqlite.org/2020/sqlite-dll-win64-x64-3310100.zip

3. Extract both archives to the same directory

Self

1. Self is contextual. There may be difficulties for understanding when need instance and when type.

def == (other : self(T)) : Bool
  self.id == other.cast(self).id
end

2. self for type reference, this for instance reference (or vice versa).

This gist is intended to give a choice between two Onyx memory models — weak and strong.

The weak model would imply possibility of memory reorderings done by the compiler, which would result in great performance by default, but create issues when doing lock-free programming.

The strong model would be simpler to newcomers, but slower, requiring to write more code to make it faster.

Note that in all examples above, async means executing in another thread, as soon as possible.

Please see the introduction to memory ordering,
