Removed `index_to_bitset` field and `_frozen` methods.
Drive-by: Added some missing docs on the `each_bit` method.
Drive-by: Put in a regular pattern: when calling `compute_id_range`, ensure `words_per_id > 0` by either asserting it or checking and returning early. (The prior code did the latter in a few cases where necessary, but debugging is much aided by the asserts.)
Fix#15019.
`call_visit_glue` is only ever called from trans_intrinsic, and the
block won't be unreachable there. Also, the comment doesn't make sense
anymore. When the code was introduced in 38fee9526a the function was
also responsible for the cleanup glue, which is no longer the case.
While we're at it, also fixed the debug message to output the right
function name.
Part of the original discussions around the `--crate-name` flag brought up that
mass confusion can arise when the flag specifies a different name than is
contained in the crate.
The current primary use case of the `--crate-name` flag is through cargo and
not requiring a `#[crate_name]` attribute, but if the `#[crate_name]` attribute
is specified it will likely go awry when the two names deviate from one another.
This commit requires that if both are provided they both match to prevent this
confusion.
Three small changes:
1. Re-organize headers in the Strings guide so they show up correctly.
2. build the strings guide with the other docs
3. include the strings guide in the list of guides
Importing from types was disallowed in #6462. Flag was set for paths whether it is a module or a type. Type flag was set when impl was seen. The problem is, for cross-crate situations, when reexport is involved, it is possible that impl is seen too late because metadata is loaded lazily.
Fix#15664.
This small patch causes the stability lint to bail out when traversing
any AST produced via a macro expansion. Ultimately, we would like to
lint the contents of the macro at the place where the macro is defined,
but regardless we should not be linting it at the use site.
Closes#15703
I decided to change it up a little today and hack out the beginning of the String guide. Strings are different enough in Rust that I think they deserve a specific guide, especially for those who are used to managed languages.
I decided to start with Strings because they get asked about a lot in IRC, and also based on discussions like this one on reddit: http://www.reddit.com/r/rust/comments/2ac390/generic_string_literals/
I blatantly stole bits from our other documentation on Strings. It's a little sparse at current, but I wanted to start somewhere.
I am not exactly sure what should go in "Best Practices," and would like the feedback from the team on this. Specifically due to comments like this one: http://www.reddit.com/r/rust/comments/2ac390/generic_string_literals/citmxb5
This should fix issue #15541. It would be good to have an test case for this would also be nice but I haven't had the time to write one. The change is very small though and it doesn't break anything in the existing test suite, so I guess we can add it without test for now.
except where trait objects are involved.
Part of issue #15349, though I'm leaving it open for trait objects.
Cross borrowing for trait objects remains because it is needed until we
have DST.
This will break code like:
fn foo(x: &int) { ... }
let a = box 3i;
foo(a);
Change this code to:
fn foo(x: &int) { ... }
let a = box 3i;
foo(&*a);

Simple usage examples for Integer methods. Also group `div_rem` and `div_mod_floor` together at the bottom of the trait, to reflect the documentation rendering.
Re-use the vector iterator to implement the chars iterator.
The iterator uses our guarantee that the string contains valid UTF-8,
but its only unsafe code is transmuting the decoded u32 into char.
5.2 Simplify example to remove hidden #[deriving(Show)].
Add example for constructing the enums.
8 Reference later sections describing rc, gc and send.
Fix for #15293.
13 Simplify BananaMania example to remove hidden code.
17 Gave an example using the derived Rand trait.
Removed references to removed 'extra' crate.
The default code model is usually unsuitable for kernels,
so we add an option to specify which model we want.
Testing for this would be fragile and very architecture specific and is better left to LLVM.
Someone asked for an example usage of this on IRC, so I tossed together the simplest one. Obviously, this isn't up to snuff, but it's better than nothing.
This makes two changes to region inference: (1) it allows region
inference to relate early-bound regions; and (2) it allows regions to be
related before variance runs. The former is needed because there is no
relation between the two regions before region substitution happens,
while the latter is needed because type collection has to run before
variance. We assume that, before variance is inferred, that lifetimes
are invariant. This is a conservative overapproximation.
This relates to #13885. This does not remove `~self` from the language
yet, however.
