Functions

< 0.20 function	0.21 equivalent
encode()	engine::general_purpose::STANDARD.encode() or prelude::BASE64_STANDARD.encode()
encode_config()	engine.encode()
encode_config_buf()	engine.encode_string()
encode_config_slice()	engine.encode_slice()
decode()	engine::general_purpose::STANDARD.decode() or prelude::BASE64_STANDARD.decode()
decode_config()	engine.decode()
decode_config_buf()	engine.decode_vec()
decode_config_slice()	engine.decode_slice()

The short-lived 0.20 functions were the 0.13 functions with config replaced with engine.

Padding

If applicable, use the preset engines engine::STANDARD, engine::STANDARD_NO_PAD, engine::URL_SAFE,
or engine::URL_SAFE_NO_PAD.
The NO_PAD ones require that padding is absent when decoding, and the others require that
canonical padding is present .

If you need the < 0.20 behavior that did not care about padding, or want to recreate < 0.20.0's predefined Configs
precisely, see the following table.

0.13.1 Config	0.20.0+ alphabet	encode_padding	decode_padding_mode
STANDARD	STANDARD	true	Indifferent
STANDARD_NO_PAD	STANDARD	false	Indifferent
URL_SAFE	URL_SAFE	true	Indifferent
URL_SAFE_NO_PAD	URL_SAFE	false	Indifferent
