Also rewrite it via composition.

Behdad Esfahbod 7675d0d3a6 [iter] Add hb_range()
hb_range() is like Python range.  hb_iota() has slightly different API.
Ie. it takes a start, instead of end.

The iter objects shouldn't not be const.  D'oh.

Behdad Esfahbod af571dbffc [meta] Replace most hb_enable_if with hb_requires
They do absolutely same thing.  hb_requires is to encode constraints,
whereas hb_enable_if is for more conditional enabling.

Behdad Esfahbod a98e4068e7 Revert "Hide symbols in hb-iter"
This reverts commit 98f14c4cdb.

Same as previous commit.
2019-04-12 22:42:44 -04:00
Behdad Esfahbod 98f14c4cdb Hide symbols in hb-iter
Painful.  All template methods need to be explicitly hidden :(.

Maybe we should switch to -fvisibility=hidden pragma.

A LOT more to go.

Behdad Esfahbod 2bd2750234 [iter] Tweak SFINAE again
Don't think we need hb_is_same().
2019-04-03 15:31:53 -07:00
Behdad Esfahbod d419a9a437 [iter] Use different SFINAE scheme to make MSVC happy
From Orvid King: TLDR; MSVC has some issues using sizeof(declval<T>()) for
SFINAE of templated types, so I just used SFINAE in a different context where
MSVC doesn't have the issue.

Behdad Esfahbod 42ab32cbba [iter] Remove passing pointer to hb_iter()
While doable with hb_deref_pointer() as well, we also would then
need to do it in a ton of places.  Not worth it / messy.
2019-04-02 18:42:51 -07:00
Behdad Esfahbod b6f29bf141 [iter] Accept pointers in hb_iter()
No idea how to avoid dupicating code.  Was hoping hb_deref_pointer()
would do it, but looks like a pointer can't bind to a universal
reference T&&.  Humm.

Behdad Esfahbod 8e34cb251a [iter] Remove unneeded &&
Next commit needs this.  I never fully get this, sigh.
2019-03-29 21:14:20 -07:00
Behdad Esfahbod 4c38a9f601 Remove hb_assign()
Not needed anymore.  We just use operator= now.
2019-03-29 20:23:07 -07:00
Behdad Esfahbod 3f36c89f2e Inline explicit_operator macro
Now that we require C++11, no need to macro.
2019-03-29 15:22:46 -07:00
Behdad Esfahbod 443db2a246 [iter] Remove hb_len()
Not planning on using it.  So remove.  Can add later if needed.
