Now we should properly resolve to a `NavigationTarget` when on top of the name of a definition. In addition this adds `name_range` field to `FileSymbol`, this further fixes goto_definition and symbol based navigation by allowing the `NavigationTarget` to actually have a `focus_range`, meaning instead of focusing on the start of the `full_range`, we can have the cursor focus on the name. e.g. goto definition ```rust fn bar() { fn foo() { } foo<|>(); } ``` Previously this would put the cursor at the start of the FN_DEF: ```rust fn bar() { <|>fn foo() { } foo(); } ``` Now when using the symbol based resolving, we'll have a proper focus range and instead put the cursor at the start of the name. ```rust fn bar() { fn <|>foo() { } foo(); } ``` This fixes #877 but doesn't contain the refactoring of the return type for `goto_definition` Co-authored-by: Ville Penttinen <[email protected]>

| * Add name_range field to FileSymbolVille Penttinen2019-02-232-7/+17
| | | | | | | | | | | | This contains the syntax range of the name itself, allowing NavigationTarget to properly set the focus_range. This should make it so that when using symbol based navigation, we should always focus on the name, instead of the full range.

| * Fix goto def not working when cursor was over the name of a defVille Penttinen2019-02-232-4/+126
| | | | | | | | | | We now allow goto_definition to return the named NavigationTarget if the cursor is on the name of a definition.
* | Fix resolution of associated method calls across cratesFlorian Diebold2019-02-233-3/+53
|/ | | | | | I think it'll be better to make the path resolution the number of unresolved segments, not the first unresolved index; then this error could simply not have happened. But I'll do that separately.

|\ | | | | | | | | | | | | | | | | | | | | | | | | | | 866: Implement basic support for Associated Methods r=flodiebold a=vipentti This is my attempt at learning to understand how the type inference works by adding basic support for associated methods. Currently it does not resolve associated types or constants. The basic idea is that `Resolver::resolve_path` returns a new `PathResult` type, which has two variants, `FullyResolved` and `PartiallyResolved`, fully resolved matches the previous behavior, where as `PartiallyResolved` contains the `PerNs<Resolution` in addition to a `segment_index` which contains the index of the segment which we failed to resolve. This index can then be used to continue inference in `infer_path_expr` using the `Type` we managed to resolve. This changes some of the previous apis, so looking for feedback and suggestions. This should enable fixing #832 Co-authored-by: Ville Penttinen <[email protected]>
| * Change resolve_path to return the fully resolved path or PerNs::noneVille Penttinen2019-02-225-36/+38
| | | | | | | | | | | | This also adds new pub(crate) resolve_path_segments which returns the PathResult, which may or may not be fully resolved. PathResult is also now pub(crate) since it is an implementation detail.

| |
| * Implement basic support for Associated Methods and ConstantsVille Penttinen2019-02-2113-50/+430
| | | | | | | | | | | | | | This is done in `infer_path_expr`. When `Resolver::resolve_path` returns `PartiallyResolved`, we use the returned `Resolution` together with the given `segment_index` to check if we can find something matching the segment at segment_index in the impls for that particular type.
