Json.dumpf

Str dumpf(
    const std::uint16_t space_num = 2, 
    const std::uint16_t depth = 0
) const noexcept;

Serializes JSON data to a formatted string and returns the result.

Parameters

• space_num: Num of spaces per indentation level (unsigned integer)
• depth: Initial indentation depth (unsigned integer, default=0)

Return Value

Returns a Str object containing the formatted JSON: - Properly indented with space_num spaces per level - Starting from specified depth level

Exception Safety

No-throw guarantee.

Complexity

Linear time (O(n)), equivalent to: 1. Creating an empty string 2. Writing formatted JSON via Json::writef()

Complexity

Content length n, recursive depth d:

O(n) usually. Maximum is O(n * d).

Because of a large amount of indentation.
