tiny.preserves.toJsonString

1/// Returns `value` as minified JSON text, allocated with `alloc`, for code that logs or sends a2/// value to a JSON consumer. The caller owns the returned bytes and frees them with `alloc`.3/// Booleans, strings and sequences become their JSON counterparts, and sets become arrays. The4/// symbol `null` becomes JSON null, and every other symbol becomes a JSON string. A byte string5/// becomes a string of lowercase hexadecimal digits. If a double is non-finite, it becomes null. An6/// integer too wide for 128 bits becomes a 64-bit number that differs from it. A dictionary becomes7/// an object: string and symbol keys become member names, and other keys are written in the text8/// syntax. A record whose label is a protocol name becomes `{"type": …}` with named fields, and9/// each field past the named ones takes the name `f` plus its index. If a record has a symbol label10/// and either zero fields or one dictionary field with string keys, the record becomes11/// `{"type": label}` plus the dictionary's entries. Any other record becomes12/// `{"__record__": label, "fields": […]}`. The discard pattern becomes `{"__discard__": true}`, and13/// captures, binds and rest patterns become `$capture`, `$bind` and `$rest` objects. An embedded14/// value becomes `{"__embedded__": "…"}` holding its pointer as a decimal string. The call frees15/// what it wrote so far on any error.16pub fn toJsonString(alloc: Allocator, value: Value) EncodeError![]const u8 {17    var out: std.Io.Writer.Allocating = .init(alloc);18    errdefer out.deinit();19    var json = JsonWriter.init(&out.writer, .minified);20    writeJson(alloc, &json, value) catch |err| switch (err) {21        error.WriteFailed => return error.OutOfMemory,22        else => return @errorCast(err),23    };24    return try out.toOwnedSlice();25}
