V8::Zone Allocator

[Methylol]

Please implement this allocator.
https://github.com/v8/v8/blob/main/src/zone/zone.h
That header file contains enough description for it.
Zone is a useful allocator for performant memory management. Acts like an stack on heap.
I wonder why there's no implementation for it in STL.

Hi,

this looks like a good candidate for another Allocator, thanks!

I plan to expand the allocator interfaces together with allowing them to be passed to library functions (what Zig has, so it's possible to, for example, override the allocator used internally for JSON parsing), and this one seems like it could have quite a few use cases.

@mosra As a remainder , do you have any plans to implement it or did you even come to any conclusions about it generally?

[mosra]

It's planned, it's just that for the past year or two the focus went into a UI library and there was little time to do anything else.

I wonder why there's no implementation for it in STL.

The description in the source file you linked looks like it is describing std::pmr::monotonic_buffer_resource, so from my understanding this is already in C++'s standard library since C++17. Is there some particular difference you notice?
