Thanks [David Simmons][david-simmons] for this awesome article!

[Tokio][tokio] 是 Rust 的開發框架，用於開發非同步 I/O 程式（asynchronous I/O，一種事件驅動的作法，可實現比傳統同步 I/O 更好的延伸性、效能與資源利用）。可惜的是，Tokio 過於精密的抽象設計，招致難以學習的惡名。即使我讀完教程後，依然不認為自己充分內化這些抽象層，以便推斷實際發生的事情。

A nonempty source file does not end in a new-line character which is not immediately preceded by a backslash character or ends in a partial preprocessing token or comment (5.1.1.2).
Token concatenation produces a character sequence matching the syntax of a universal character name (5.1.1.2).
A program in a hosted environment does not define a function named main using one of the specified forms (5.1.2.2.1).
A character not in the basic source character set is encountered in a source file, except in an identifier, a character constant, a string literal, a header name, a comment, or a preprocessing token that is never converted to a token (5.2.1).
An identifier, comment, string literal, character constant, or header name contains an invalid multibyte character or does not
