std.json.Generator

class pub Generator

A type for turning a Json value into a JSON string.

This type is used by Json.to_string and Json.to_pretty_string. Unless you want to use custom indentation, it's recommended to use these methods instead of using Generator directly.

  )
}

fn pub static new(indent: Int) -> Generator
