How to check if a character is a Unicode (not just ASCII) newline character in Rust?

Question

Each programming language has its own interpretation \nand \r. Unicode supports multiple characters that can represent a new line.

From the Rust link :

White space is one of the characters U + 006E (n), U + 0072 (r), or U + 0074 (t), denoting Unicode values ​​U + 000A (LF), U + 000D (CR), or U + 0009 (HT ) respectively.

Based on this statement, I would say that the Rust character is a newline if it is either \nor \r. On Windows, this can be a combination of \rand \n. However, I am not sure.

What about the next one?

• Next line character (U + 0085)
• Line Separator Character (U + 2028)
• Paragraph separator character (U + 2029)

In my opinion, we are losing something like char.is_new_line(). I looked through the Unicode Character Categories , but could not find a definition for new lines.

Should I come up with my own definition of what a Unicode newline character is?
