Method resolve_code_action

src/code_actions/mod.rs:248–375

Handle a `codeAction/resolve` request. The editor sends back a `CodeAction` that was previously returned by [`handle_code_action`](Self::handle_code_action) with a `data` field but no `edit`. This method deserializes the data, computes the full workspace edit, and returns the completed action. For PHPStan quickfixes the matched diagnostic is also eagerly removed from the cache and updated diagn

(&self, mut action: CodeAction)

    /// removed from the cache and updated diagnostics are returned via
    /// the `diagnostics_to_republish` output parameter.
