This doesn't work:
import std/strformat
import results
proc foo():Result[void,cstring] =
let res = -1
err(&"failed {r}")
Run
because Result[T,cstring] is special-cased to 'avoid dangling cstring pointers'
is there a simple test case that you can share that shows the danger here?
is the only safe option to use Result[T,string] internally, and convert to
cstring at the ffi boundary?
i'm already exposing a faked `Result<T>` c++ class, lifetimes are gonna be a
bitch anyway, i think i've answered my own question and i should put the
conversion in the `error` accessor method, but if you've got any wisdom on the
matter, i'd appreciate it.
