Does Haskell's `Data.Vector.Mutable.unsafeNew` zero the memory? -


the docs says new "creates mutable vector of given length" , unsafenew "creates mutable vector of given length. length not checked."

however this resolved github issue indicates unsafenew not 0 memory while new does.

which 1 it?

no, not in general. if click through source pretty clear:

https://hackage.haskell.org/package/vector-0.11.0.0/docs/src/data-vector-generic-mutable.html#new

new unsafenew addition of basicinitialize.

(side note: core of problem entanglement of user input firing “expensive computations”. therefore, cannot separate both in 2 scripts, , letting 1 spawning other daemon.) the command screen may you. use screen -l create new session , run application. after inputting data, can press " ctrl-a " , press " d " on keyboard detach session. now
