7649d1c2a8 shadow: complete coverage of "contains_self" checker 2015-09-02 18:24:46 +02:00

6b589681c9 methods: allow multiple self kinds for "is_" methods 
These can be static method predicates.  (Found one in rust-copperline,
called Term::is_unsupported_term().)

846c164709 don't say "did you mean to" - use the standard "consider..." 
"Did you mean to ..." sounds a bit condescending to me, since
if I meant to write "if let" I probably wouldn't have written "match" :)

signed type of the same size.

8a10440641 utils: add match_type() helper function

 2015-08-21 19:24:38 +02:00

a437936d49 all: put often used DefPaths into utils as consts 
Also remove the "use xxx;" blocks to ensure import paths don't change.
They don't work anyway since stuff may still be re-exported at the old
location, while we need the "canonical" location for the type checks.

Plus, the test suite catches all these cases.

ad0bc66402 Added support for isize/usize in the CastPass lint pass. 
Extracted the match that determines an integer types's size in a
utility function and implemented support for usize/isize.
Added a needed feature to the crate root.
Added some tests to cover those cases, and a test I previously forgot.
Silenced two errors signaled by dogfood.sh in unicode.rs.

lint.
Updated the test case to reflect changes.
