Bananymous 891144dac1 BAN: Iterators are now single general type with CONST template
This allows us to use the same base class for iterator and
const_iterator which were practically the same code.
2023-07-12 13:35:21 +03:00
Bananymous 41e7b53903 BAN: add either_or and either_or_t
This allows you to select type depending on constexpr evaluatable
boolean

Bananymous 6b0920e8c0 BAN: Implement ConstIteratorDouble and add it to HashMap

not return non-const references.
2023-07-12 11:41:05 +03:00
Bananymous 4285729d5c BAN: Generalize HashMapIterator to IteratorDouble
This iterator should be able to iterate any container within container
with type iterator defined.

This also fixed bug if first entry in outer container is empty container.

Bananymous 74c79c7eff Kernel: Rewrite whole device structure
We now have DevFileSystem which is derived from RamFileSystem. All
devices are RamInodes. We don't have separate DeviceManager anymore.
To iterate over devices, you can loop througn every inode in devfs.
