Convert a value to a JSON string.

This function with convert value types as follows:

  • Gleam’s Nil to JSON’s null.
  • Gleam’s True to JSON’s true.
  • Gleam’s False to JSON’s false.
  • Gleam’s String to JSON’s string.
  • Gleam’s Int and Float to JSON’s number.
  • Gleam’s option.Some will unwarp its internal value and be converted depend on its type.
  • Gleam’s option.None to JSON’s null.
  • Gleam’s tuple, List and set.Set to JSON’s array and all of its values inside with also be converted recursively.
  • Gleam’s dict.Dict to JSON’s object and all of its keys/values with also be converted recursively.
  • Gleam’s BitArray to JSON’s object of { bit_size: Number, byte_size: Number, bit_offset: Number, raw_buffer: Array<Number> }.
  • Gleam’s custom type to JSON’s object with its type variant name in type: String and all of its fields be converted recursively (unlabeled fields will be numbered instead).
  • Other type will be keep the same.
