Rustの演算子の優先順位 Operator precedence

次の表で、演算子を優先順位降順に並べる。
- 単項演算子は二項演算子より優先されることが分かる。
  - より正確には、後置単項演算子 > 前置単項演算子 > 二項演算子の順。
- 「非結合」演算子では、その結合を丸括弧 (,) で明示しないと文法エラーとなる。
  - a == b == c - Error
  - (a == b) == c - OK
フィールド演算子.は?より強い。よって &self.hoge?は&((self.hoge)?)となる。

How to install and run postgresql in conda

	This gist I write, because I couldn't find step by step instructions
	how to install and start postgresql locally (using conda within a conda environment - with the result
	that you can run it without sudo/admin rights on your machine!)
	and not globally in the operating system (which requires sudo/admin rights on that machine).

	I hope, this will help especially people new to postgresql (and those who don't have sudo/admin rights on a specific machine but want
	to run postgresql there)!
