Provide API to get only specific directory

[Shatur]

With dirs crate I can get any directory directly. But directories provides structs and parses all directories at once. Users usually want to get a single directory. I would suggest to create separate functions as in dirs crate.

Hey Hennadii,

the intention of this design was to allow a user to create this struct once with the right parameters for the given application and then be able to use the derived paths for the applications' needs, while having the guarantee that all paths where computed consistently (i. e. at the same time during the construction of struct).

In the case only a single directory is needed, it's perfectly fine to use dirs instead.

What's the source of your concerns?

Cheers,

Simon

But I most of the application doesn't need all of them. This is why I suggested to allow to get directories separately. Or evaluate directories lazily.

dirs is great. But this crate provides project directories which I need.

I recently discovered standard_paths crate which have the described design. So if you disagree with the suggestion - feel free to close the issue.

As soon as applications use more than one, it should already be cost-effective, because the expensive operations are only executed once.

Not sure I understand, that crate appears to be using roughly the approach. Am I missing something?

You doing it once, but you create a structure with 7 directories when usually an application need 1-2. I would also create it once, but with needed directories.

I just mentioned that I already found a library (was in the README) that allow to find only specified directories as I suggested.
