844: Refactor find_all_refs to return ReferenceSearchResult r=vipentti a=vipentti

This refactors `find_all_refs` to return a new `ReferenceSearchResult` based on feedback in #839.

There are few questions/notes regarding the refactor:

1. Introducing `NavigationTarget::from_bind_pat` this simply forwards the call to `NavigationTarget::from_named`, could we just expose `from_named` directly as `pub(crate)` ?
2. Added an utility method `NavigationTarget::range` since there were few places where you would use `self.focus_range.unwrap_or(self.full_range)`
3. Implementing `IntoIterator` for `ReferenceSearchResult`. This turns `ReferenceSearchResult` into an iterator over `FileRanges` and allows previous code to mostly stay as it was based on the order that `find_all_refs` previously had (declaration first and then the references). I'm not sure if there is a way of doing the conversion to `IntoIter` without the allocation of a new vector
4. Is it possible to have a binding without a name? I'm not sure if the `NavigationTarget::from_bind_pat` can cause some edge-cases that previously were ok



This fixes #835.

Rust Analyzer

Build Status

Rust Analyzer is an experimental modular compiler frontend for the Rust language. It is a part of a larger rls-2.0 effort to create excellent IDE support for Rust. If you want to get involved, check rls-2.0 working group repository:

https://github.com/rust-analyzer/WG-rls2.0

Work on the Rust Analyzer is sponsored by

Ferrous Systems

Quick Start

Rust analyzer builds on Rust >= 1.31.0 and uses the 2018 edition.

# run tests
$ cargo test

# show syntax tree of a Rust file
$ cargo run --package ra_cli parse < crates/ra_syntax/src/lib.rs

# show symbols of a Rust file
$ cargo run --package ra_cli symbols < crates/ra_syntax/src/lib.rs

# install the language server
$ cargo install-lsp
or
$ cargo install --path crates/ra_lsp_server

See these instructions for VS Code setup and the list of features (some of which are VS Code specific).

Debugging

See these instructions on how to debug the vscode extension and the lsp server.
