Release Notes

marshallpierce/rust-base64 (base64)

v0.22.1

Compare Source

• Correct the symbols used for the predefined alphabet::BIN_HEX.

v0.22.0

Compare Source

• DecodeSliceError::OutputSliceTooSmall is now conservative rather than precise. That is, the error will only occur if the decoded output cannot fit, meaning that Engine::decode_slice can now be used with exactly-sized output slices. As part of this, Engine::internal_decode now returns DecodeSliceError instead of DecodeError, but that is not expected to affect any external callers.
• DecodeError::InvalidLength now refers specifically to the number of valid symbols being invalid (i.e. len % 4 == 1), rather than just the number of input bytes. This avoids confusing scenarios when based on interpretation you could make a case for either InvalidLength or InvalidByte being appropriate.
• Decoding is somewhat faster (5-10%)

v0.21.7

Compare Source

• Support getting an alphabet's contents as a str via Alphabet::as_str()

v0.21.6

Compare Source

• Improved introductory documentation and example

v0.21.5

Compare Source

• Add Debug and Clone impls for the general purpose Engine

v0.21.4

Compare Source

• Make encoded_len const, allowing the creation of arrays sized to encode compile-time-known data lengths

v0.21.3

Compare Source

• Implement source instead of cause on Error types
• Roll back MSRV to 1.48.0 so Debian can continue to live in a time warp
• Slightly faster chunked encoding for short inputs
• Decrease binary size

v0.21.2

Compare Source

• Rollback MSRV to 1.57.0 -- only dev dependencies need 1.60, not the main code

v0.21.1

Compare Source

• Remove the possibility of panicking during decoded length calculations
• DecoderReader no longer sometimes erroneously ignores
  padding #​226

Breaking changes

• Engine.internal_decode return type changed
• Update MSRV to 1.60.0

v0.21.0

Migration

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

v0.20.0

Compare Source

Breaking changes

• Update MSRV to 1.57.0
• Decoding can now either ignore padding, require correct padding, or require no padding. The default is to require
  correct padding.
  • The NO_PAD config now requires that padding be absent when decoding.

0.20.0-alpha.1

Breaking changes

• Extended the Config concept into the Engine abstraction, allowing the user to pick different encoding / decoding
  implementations.
  • What was formerly the only algorithm is now the FastPortable engine, so named because it's portable (works on
    any CPU) and relatively fast.
  • This opens the door to a portable constant-time
    implementation (#​153,
    presumably ConstantTimePortable?) for security-sensitive applications that need side-channel resistance, and
    CPU-specific SIMD implementations for more speed.
  • Standard base64 per the RFC is available via DEFAULT_ENGINE. To use different alphabets or other settings (
    padding, etc), create your own engine instance.
• CharacterSet is now Alphabet (per the RFC), and allows creating custom alphabets. The corresponding tables that
  were previously code-generated are now built dynamically.
• Since there are already multiple breaking changes, various functions are renamed to be more consistent and
  discoverable.
• MSRV is now 1.47.0 to allow various things to use const fn.
• DecoderReader now owns its inner reader, and can expose it via into_inner(). For symmetry, EncoderWriter can do
  the same with its writer.
• encoded_len is now public so you can size encode buffers precisely.

v0.13.1

Compare Source

• More precise decode buffer sizing, avoiding unnecessary allocation in decode_config.

♻ Renovate will retry this branch, including artifacts, only when one of the following happens:

• any of the package files in this branch needs updating, or
• the branch becomes conflicted, or
• you click the rebase/retry checkbox if found above, or
• you rename this PR's title to start with "rebase!" to trigger it manually

The artifact failure details are included below:

perhaps a crate was updated and forgotten to be re-vendored?
