classmethod encode(value: Any, charset: Charset | None = Charset.UTF8, format: Format | None = Format.RFC3986) → str

static serialize_date(dt: datetime) → str

Serialize a datetime object to an ISO 8601 string.

qs_codec.utils.str_utils module

Utility functions for working with strings.

qs_codec.utils.str_utils.code_unit_at(string: str, index: int) → int

Returns the 16-bit UTF-16 code unit at the given index.

This function first encodes the string in UTF-16 little endian format, then calculates the code unit at the given index. The code unit is calculated by taking the byte at the index and adding it to 256 times the next byte. This is because UTF-16 represents each code unit with two bytes, and in little endian format, the least significant byte comes first.
