Description

A regular source of annoyance for me is the flurry of error messages when I am resolving a merge conflict. There are syntax errors everywhere which make the code hard to read. Could rust-analyzer notice merge conflicts and refrain from emitting too many syntax errors? Maybe just a single error "syntax error: this is a merge conflict".
More far-fetched would be if ra could actually process both versions in parallel (or all 3 of them in 3-way merges), but I won't hold my breath x)

Research direction

The issue names no files, tests, or entry points. Start by locating rust-analyzer's merge-conflict handling and syntax-diagnostic emission, then clarify whether the goal is one diagnostic or parallel parsing of conflict versions. Done means merge conflicts no longer produce a distracting flood of syntax errors.
