The convention is to use lowercase for the module name:
module myclass;
struct MyClass {}
Using lowercase letters for module names (and their respective
file names!!) also prevents weird errors when different OSes
treat lower/capital case letters differently which can
sometimes lead to modules not being found.
So from my experience: always use lower-case letters for
modules and the file names.
I understood, thank you!

Hmm, I thought that name of class should match name of file...
And how to name a file that contains only one class/struct?
Like in my case. What usually true D coders do?)

Modules usually named after their purpose. Like std.stdio for IO stuff, std.file for file utilities, and complex example is std.algorithm.search for various searching algorithms which is a part of more global std.algorithm package (importing it also brings in several other std.algorithm.* modules). Not sure about your use case, but seems like parser.d or args.d or argsparser.d (names best to keep lower case in case of OS or FS specific quirks, this is the convention) Also if you need ready to use arguments parser check this one https://dlang.org/phobos/std_getopt.html

Of course function "parse" doesn't exist in this module. But it
exists inside struct "MyClass"!
What should I do to import my struct correctly?
That's just name collision, because module is a valid symbol you
need to be specific about what you are trying to access.
Try selective import instead
import MyClass : MyClass;
Of course if there is more symbols needed you have to specify
them as well after a comma.
Another option to save up on typing is renamed imports
import mc = MyClass;
mc.MyClass.parse(...)
