Brendan Hansknecht (May 19 2023 at 19:22): Brendan Hansknecht (May 19 2023 at 19:22):If I write a when over strings, will it use a tree for smart matching?
when str is
"aaa" -> ...
"aab" -> ...
"ac" -> ...
_ -> ...
Essentially would be above code generate a character by character tree based match. So if the first character isn't a, it will just go straight to the _ case.
Ayaz Hafiz (May 19 2023 at 19:32):by default the compiler does not do so; optimizations might turn this into a tree comparison though.
Brendan Hansknecht (May 21 2023 at 03:36):What do we do for lists of bytes?
So the same function as above, but ['a', 'a', 'a', ..] or similar?
Ayaz Hafiz (May 21 2023 at 04:30):lists compile to prefix trees
