* | Add new TYPE_BOUND_LIST and TYPE_BOUND syntax kindsVille Penttinen2019-03-302-0/+81
| | | | | | | | | | | | These are now used when parsing type bounds. In addition parsing paths inside a bound now does not recursively parse paths, rather they are treated as separate bounds, separated by +.

|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1034: HIR diagnostics API r=matklad a=matklad This PR introduces diagnostics API for HIR, so we can now start issuing errors and warnings! Here are requirements that this solution aims to fulfill: * structured diagnostics: rather than immediately rendering error to string, we provide a well-typed blob of data with error-description. These data is used by IDE to provide fixes * open set diagnostics: there's no single enum with all possible diagnostics, which hopefully should result in better modularity The `Diagnostic` trait describes "a diagnostic", which can be downcast to a specific diagnostic kind. Diagnostics are expressed in terms of macro-expanded syntax tree: they store pointers to syntax nodes. Diagnostics are self-contained: you don't need any context, besides `db`, to fully understand the meaning of a diagnostic. Because diagnostics are tied to the source, we can't store them in salsa. So subsystems like type-checking produce subsystem-local diagnostic (which is a closed `enum`), which is expressed in therms of subsystem IR. A separate step converts these proto-diagnostics into `Diagnostic`, by merging them with source-maps. Note that this PR stresses type-system quite a bit: we now type-check every function in open files to compute errors!

|\ | | | | | | | | | | | | | | | | | | | | | | | | 1036: Assist to flip equality (==) and negated equality (!=) operands. r=matklad a=marcogroppo This PR adds an assist to flip the equality operands. I hope this is the right way to do this (I'm a newbie...) Fixes #1023. Co-authored-by: Marco Groppo <[email protected]>

|\ | | | | | | | | | | | | | | | | | | | | | | 991: Use Marker argument for item parsers r=matklad a=pcpthm Before doing this for expressions, I found that the pattern (Marker argument) should be applied to the item parsers because visiblity and modifiers are parsed in a separate function. Fixed some parser bugs: - Fix pub_expr: `pub 42;` was allowed. - Fix incorrect parsing of crate::path: incorrectly parsed as `crate` as a visibility. Co-authored-by: pcpthm <[email protected]>
