build(deps): bump base64 from 0.20.0 to 0.21.0

[dependabot[bot]]

Bumps base64 from 0.20.0 to 0.21.0.

Changelog

Sourced from base64's changelog.

0.21.0

(not yet released)

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

0.21.0-rc.1

• Restore the ability to decode into a slice of precisely the correct length with Engine.decode_slice_unchecked.
• Add Engine as a pub use in prelude.

0.21.0-beta.2

Breaking changes

• Re-exports of preconfigured engines in engine are removed in favor of base64::prelude::... that are better suited to those who wish to use the entire path to a name.

Tried update our use of base64::encode to follow what was done in https://github.com/bottlerocket-os/bottlerocket-update-operator/pull/403/files, but for some reason I am getting compile errors:

error[E0433]: failed to resolve: could not find `base64_engine` in the crate root
  --> model/src/test_manager/mod.rs:70:27

   |                           ^^^^^^^^^^^^^ could not find `base64_engine` in the crate root

May need some help from someone with a little stronger rust knowledge than me.

I might would hold off on this one until the crates that currently use base64 0.20.0 move to 0.21.0. Seems a bit silly to pull 3 versions if there isn't an specific reason for upgrading.

We do still have to figure out what to do about base64::encode as we're going to run into this issue in our other projects as well.

It might be nice to revisit this, as more crates have moved to 0.21.0.

[dependabot[bot]]

A newer version of base64 exists, but since this PR has been edited by someone other than Dependabot I haven't updated it. You'll get a PR for the updated version as normal once this PR is merged.

[dependabot[bot]]

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
