Creates a new string.
@param value [String] See {#value} @param type [Symbol] See {#type} @param deprecated_interp_equivalent [String?]
If this was created via a potentially-deprecated string interpolation, this is the replacement expression that should be suggested to the user.
Calls superclass method

quote(contents, opts = {})

Returns the quoted string representation of ‘contents`.
@options opts :quote [String]
The preferred quote style for quoted strings. If `:none`, strings are always emitted unquoted. If `nil`, quoting is determined automatically.
@options opts :sass [String]
Whether to quote strings for Sass source, as opposed to CSS. Defaults to `false`.
