generate_csv - generated CSV header is always alphabetically ordered

[jqnatividad]

First off, thanks for this awesome library!

However, the generated csv's headers are alphabetically ordered.

The generated data itself is OK.

@jqnatividad Thank you for submitting this bug. I'll take a look at it.

[dsietz]

Looks like the root cause is the the BTreeMap doesn't preserve the order of insertion.

[jqnatividad]

As I understand it, BTreeMap sorts the keys.

Perhaps, use https://github.com/bluss/indexmap instead?

It looks like that crate will work. Thanks for the suggestion. It will be a breaking change because any saved DataSampleParsers (DSP) from the prior version will not be able to be loaded from file into this new DataSampleParser struct.

Time for test-data-generation 0.3 perhaps? 😉

I'm keen to use it to power test data generation for qsv.

[dsietz]

Fix in development and passing. Will be included in release 0.3.0

[dsietz]

version 0.3.0 has been published to crates.io

[dsietz]

This issue is resolved.

Hi @dsietz , just wanted to let you know that I just published qsv 0.22.0 with the generate command powered by test-data-generation.

Once again, thanks for this awesome library and I look forward to your feedback!

[dsietz]

@jqnatividad You're welcome. And much success with qsv.
