Replacement for ArrayList.fixedWriter

[serene turret]

I'm confused, what is the replacement for std.array_list.Managed(u8).fixedWriter? My usecase is that I'm trying to convert an integer to a string in a loop but I know the max length of the string on each iteration of the loop, so I'm clearing the list and then reserving that amount before converting to the string

std.Io.Writer.fixed?

actually std.Io.Writer.Allocating prob better

depends on your setups

Does Allocating support a clear operation? (without unallocating)

yes

Hm that's probably good enough for now

Even though it could reallocate

ya but in theory the print function could reallocate even though it never will

but at this point I think that's more effort than it's worth to fix

[delicate flare]

if you dont want to allocate use fixed, you can use consume to reset it.

[errant scroll]

i think he wants to be able to reallocate if needed, but only at the start of each loop

which Allocating is perfect for :)
