This PR introduces `isize` and `usize` modules to `core` and `std`, and
deprecates the existing `int` and `uint` modules. The rustdoc primitive
type links now point to these new modules.
Due to deprecation this is a:

This removes a large array of deprecated functionality, regardless of how
recently it was deprecated. The purpose of this commit is to clean out the
standard libraries and compiler for the upcoming alpha release.
Some notable compiler changes were to enable warnings for all now-deprecated
command line arguments (previously the deprecated versions were silently
accepted) as well as removing deriving(Zero) entirely (the trait was removed).
The distribution no longer contains the libtime or libregex_macros crates. Both
of these have been deprecated for some time and are available externally.

This small patch stabilizes the names of all integer modules (including
`int` and `uint`) and the `MIN` and `MAX` constants. The `BITS` and
`BYTES` constants are left unstable for now.

followed by a semicolon.
This allows code like `vec![1i, 2, 3].len();` to work.
This breaks code that uses macros as statements without putting
semicolons after them, such as:
fn main() {
...
assert!(a == b)
assert!(c == d)
println(...);
}
It also breaks code that uses macros as items without semicolons:
local_data_key!(foo)
fn main() {
println("hello world")
}
Add semicolons to fix this code. Those two examples can be fixed as
follows:
fn main() {
...
assert!(a == b);
assert!(c == d);
println(...);
}
local_data_key!(foo);
fn main() {
println("hello world")
}
RFC #378.
Closes #18635.

Spring cleaning is here! In the Fall! This commit removes quite a large amount
of deprecated functionality from the standard libraries. I tried to ensure that
only old deprecated functionality was removed.
This is removing lots and lots of deprecated features, so this is a breaking
change. Please consult the deprecation messages of the deleted code to see how
to migrate code forward if it still needs migration.

ImmutableVector -> ImmutableSlice
ImmutableEqVector -> ImmutableEqSlice
ImmutableOrdVector -> ImmutableOrdSlice
MutableVector -> MutableSlice
MutableVectorAllocating -> MutableSliceAllocating
MutableCloneableVector -> MutableCloneableSlice
MutableOrdVector -> MutableOrdSlice
These are all in the prelude so most code will not break.

The following are unstable:
- core::int, i8, i16, i32, i64
- core::uint, u8, u16, u32, u64
- core::int::{BITS, BYTES, MIN, MAX}, etc.
- std::int, i8, i16, i32, i64
- std::uint, u8, u16, u32, u64
The following are experimental:
- std::from_str::FromStr and impls - may need to return Result instead of Option
- std::int::parse_bytes, etc. - ditto
- std::num::FromStrRadix and impls - ditto
- std::num::from_str_radix - ditto
The following are deprecated:
- std::num::ToStrRadix and imples - Wrapper around fmt::radix. Wrong name (Str vs String)

This commit adds support in rustdoc to recognize the `#[doc(primitive = "foo")]`
attribute. This attribute indicates that the current module is the "owner" of
the primitive type `foo`. For rustdoc, this means that the doc-comment for the
module is the doc-comment for the primitive type, plus a signal to all
downstream crates that hyperlinks for primitive types will be directed at the
crate containing the `#[doc]` directive.
Additionally, rustdoc will favor crates closest to the one being documented
which "implements the primitive type". For example, documentation of libcore
links to libcore for primitive types, but documentation for libstd and beyond
all links to libstd for primitive types.
This change involves no compiler modifications, it is purely a rustdoc change.
The landing pages for the primitive types primarily serve to show a list of
implemented traits for the primitive type itself.
The primitive types documented includes both strings and slices in a semi-ad-hoc
way, but in a way that should provide at least somewhat meaningful
documentation.
Closes #14474

In an attempt to phase out the std::num::strconv module's string formatting
functionality, this commit reimplements some provided methods for formatting
integers on top of format!() instead of the custom (and slower) implementation
inside of num::strconv.
Primarily, this deprecates int_to_str_bytes_common
|
|
API Changes:
- &[T] and ~[T] no longer support the addition operator (+)
|
|
This implements all traits inside of core::num for all the primitive types,
removing all the functionality from libstd. The std modules reexport all of the
necessary items from the core modules.

See #11273 and #13318

Also rename `next_power_of_two_opt` to `checked_next_power_of_two`.
|
|
`Times::times` was always a second-class loop because it did not support the `break` and `continue` operations. Its playful appeal was then lost after `do` was disabled for closures. It's time to let this one go.
|
|
The following are renamed:
* `min_value` => `MIN`
* `max_value` => `MAX`
* `bits` => `BITS`
* `bytes` => `BYTES`
Fixes #10010.

One less trait in std::num, and three less exported in the prelude.

This commit uniforms the short title of modules provided by libstd,
in order to make their roles more explicit when glancing at the index.

Like next_power_of_two, but returns None on overflow.
|
|
This follows the same pattern as the other numeric trait impls, and reduces the clutter in std::num.
|
|
Moves the Times trait to num while the question of whether it should
exist at all gets hashed out as a completely separate question.
|

|
|
Change the former repetition::
for 5.times { }
to::
do 5.times { }
.times() cannot be broken with `break` or `return` anymore; for those
cases, use a numerical range loop instead.
