Subject: [Caml-list] caml match optimization
Date: Tue, 16 Oct 2012 23:54:13 +0200	[thread overview]
Message-ID: <507DD785.8030300@libertysurf.fr> (raw)

Hello,
I have this code sample :

let apply_foo         = apply_all_elements foo foo_struct
let apply_bar         = apply_all_elements bar bar_struct
let apply_baz         = apply_all_elements baz baz_struct
[...]
let apply_biz         = apply_all_elements biz biz_struct



If I make a function such as :

let apply2 = function
| `Foo -> apply_all_elements foo foo_struct
| `Bar -> apply_all_elements bar bar_struct
| `Baz -> apply_all_elements baz baz_struct
[...]
| `Biz -> apply_all_elements biz biz_struct


How much is "apply2" inefficient ?
does caml tests for 20 elements if `Biz is number 21 ?
Or does ocaml try to convert the list of elements in a tree internally ? 
(to optimise access) or something else ?

Regards,
William
