The conclusion is written in the first: in the go language is not inclined to use single quotation marks to represent strings, use double quotation marks or anti-quotation marks as needed.

A go language string is a constant sequence of arbitrary bytes. The string type of the go language is inherently different from the string type of other languages. Java's string, C + + std::string, and Python3 's str type are all just fixed-width character sequences, while the go language string is a UTF-8-encoded, variable-width sequence of characters, each of which is represented by one or more bytes .

string literals in the go language are created using double or inverted quotation marks:

    • Double quotation marks are used to create resolvable string literals (which support escaping, but cannot be used to refer to multiple lines);
    • Anti-quotes are used to create native string literals , which may consist of multiple lines (no escape sequences are supported), and native string literals are used to write multiline messages, HTML, and regular expressions.

There is forms:raw string literals and interpreted string literals.

  • Raw string literals is character sequences between back quotes, as in foo  .
  • Interpreted string literals is character sequences between double quotes, as in "bar".

A rune literal represents a Rune constant, an integer value identifying a Unicode code point. A Rune Literal is expressed as one or more characters enclosed in single quotes, as in ' x ' or ' \ n '. Within the quotes, any character could appear except newline and unescaped single quote. A Single quoted character represents the Unicode value of the character itself, while multi-character sequences beginning With a backslash encode the values in various formats.


According to the information I found and the situation I encountered, the single quotes of the go language are generally used to denote "rune literal" , the code point literal.
