GdalType as Pulic about gdal

[jdroenner]

Since the GdalDatatatype in gdal-sys is pub, GdalType can probably also be pub. Do you want to create a pull request?

[jdroenner]

I'm not really sure if we want GdalType to be public. Let me think about the implications :)

[jdroenner]

Since Array2 is the obvious data-structure for raster data, i guess we should add such method directly to rust-gdal. However, we should use a feature "ndarray" to allow disabling.

Do you think this would work for your use-case?

[austinstig]

yes... that would be really great!

[jdroenner]

Great :) If you already have a matching method feel free to create a pull request. Otherwise i will see if i have time to write something :)

[austinstig]

No problem. I'll work on it.

[austinstig]

Not sure how great it is but I have submitted PR. Thanks!

[jdroenner]

Great! thank you :) I will look at it as soon as possible (when i have some free time).

I have another use case that I think would benefit from GdalType being public. I'm trying to write a function that, given a sequence of bands, combines them into a dataset.

Since the GDAL data type isn't part of the RasterBand type, I think I need to hard-code the band type in the caller. I think the signature might look something like

fn combine<T: GdalType>(b1: &RasterBand, b2: &RasterBand, ...) -> Result<Dataset, Error>

Is there an alternative that I should consider?
