Custom allocator support #34

Open thomcc opened 2 years ago

thomcc commented 2 years ago

We could define a custom trait (see how hashbrown does this) to support it prior to the unstable trait landing. This would (at the very least) allow testing allocation fallibility[^1], if nothing else.

That said, this is a non-trivial amount of work that seems a bit pointless at the moment.

[^1]: Admittedly, the amount of code that it would allow testing is very small, and the code in question is very straightforward — just a few lines which do nothing but return errors to their caller.

I think it is not worth it to define a custom trait, but there's no reason we couldn't support core::alloc::Allocator once it is stable.
