5283a8b reworks the TreeMap lazy iterator to use `&mut` again, which closes#4763. It gets the performance of the set methods back in the same ballpark that it was pre-INHTWAMA which is nice. These can be turned back into methods eventually.
e5b6334 removes the transitional smallintmap attributes which closes#4737.
Also adds Rng::gen() for generically generating any type that implements the Rand trait. There's no way to generate things with a length (for e.g. strings or vectors), because I can't think of an elegant way to do that. Maybe have a RandLen trait that inherits Rand?
This can be used for a quickcheck mechanism I'm working on.
Calling it on a special value now causes a failure, however `to_str_radix_special()` is provided which can be
used if those values are expected, and which returns a tupel to allow differentating them.
Also fixed all conflicting calls of the old functions in the rest of the codebase.
The set of string conversion functions for each float type now consists of those items:
- to_str(), converts to number in base 10
- to_str_hex(), converts to number in base 16
- to_str_radix(), converts to number in given radix
- to_str_exact(), converts to number in base 10 with a exact number of trailing digits
- to_str_digits(), converts to number in base 10 with a maximum number of trailing digits
- implementations for to_str::ToStr and num::ToStrRadix
- from_str(), parses a string as number in base 10 including decimal exponent and special values
- from_str_hex(), parses a string as a number in base 16 including binary exponent and special values
- from_str_radix(), parses a string as a number in a given base excluding any exponent and special values
- implementations for from_str::FromStr and num::FromStrRadix
- Moved ToStr implementation of unsigned integers to uint-template.rs.
- Marked the `str()` function as deprecated.
- Forwarded all conversion functions to `core::num::to_str_common()`
and `core::num::from_str_common()`.
- Fixed most places in the codebase where `to_str()` is being used.
- Added uint-template to_str and from_str overflow tests.
- Moved ToStr implementation of integers to int-template.rs.
- Marked the `str()` function as deprecated.
- Forwarded all conversion functions to `core::num::to_str_common()`
and `core::num::from_str_common()`.
- Fixed most places in the codebase where `to_str()` is being used.
- Added int-template to_str and from_str overflow tests.
They unify the different implementations that exists in int-template.rs, uint-template.rs and float.rs into one pair of functions, which are also in principle usable for anything that implements the necessary numeric traits. Their usage is somewhat complex due to the large amount of arguments each one takes, but as they're not meant to be used directly that shouldn't be a problem.
Changes:
- Refactor move mode computation
- Removes move mode arguments, unary move, capture clauses
(though they still parse for backwards compatibility)
- Simplify how moves are handled in trans
- Fix a number of illegal copies that cropped up
- Workaround for bug involving def-ids in params
(see details below)
Future work (I'll open bugs for these...):
- Improve error messages for moves that are due
to bindings
- Add support for moving owned content like a.b.c
to borrow check, test in trans (but I think it'll
"just work")
- Proper fix for def-ids in params
Def ids in params:
Move captures into a map instead of recomputing.
This is a workaround for a larger bug having to do with the def-ids associated
with ty_params, which are not always properly preserved when inlining. I am
not sure of my preferred fix for the larger bug yet. This current fix removes
the only code in trans that I know of which relies on ty_param def-ids, but
feels fragile.
