mnemosine.ids._encode

Kind: function

Signature

_encode(value: int, bits: int) -> str

Documentation

Encode an integer as Crockford base32 over a fixed number of bits.

Splits value into 5-bit groups (least significant first) and maps each group to a character from _ALPHABET. The width is ceil(bits / 5); any bits above bits are silently ignored.

Args:

• value (int): The non-negative integer to encode.
• bits (int): The total bit width the encoding should cover.

Returns:

• str: The fixed-width Crockford base32 representation.

Example:

>>> from mnemosine.ids import _encode
>>> _encode(26, 5)   # 26 == 11010 -> alphabet[26] == 'Q'
'Q'
