Enum DisplayFormat

pub enum DisplayFormat {
    Repl,
    Expression,
    Eval,
}

Variants

Repl

Display the value as a string that can be passed to a JavaScript REPL. In this mode, the final statement of the string is not terminated with a semicolon and may be wrapped in parentheses to make it an expression statement.

This is usually the clearest way to display a value to a user.

Expression

Display the value as a string that can be used in an expression position, such as the RHS of a function. If intermediate variables are needed, the entire string is wrapped in an IIFE.

Eval

Display the value as a string that can be passed to eval(). One should use indirect eval (for example (0, eval)()) to avoid polluting the current scope.
