-// Feature: Structural Search and Replace
-//
-// Search and replace with named wildcards that will match any expression, type, path, pattern or item.
-// The syntax for a structural search replace command is `<search_pattern> ==>> <replace_pattern>`.
-// A `$<name>` placeholder in the search pattern will match any AST node and `$<name>` will reference it in the replacement.
-// Within a macro call, a placeholder will match up until whatever token follows the placeholder.
-//
-// All paths in both the search pattern and the replacement template must resolve in the context
-// in which this command is invoked. Paths in the search pattern will then match the code if they
-// resolve to the same item, even if they're written differently. For example if we invoke the
-// command in the module `foo` with a pattern of `Bar`, then code in the parent module that refers
-// to `foo::Bar` will match.
-//
-// Paths in the replacement template will be rendered appropriately for the context in which the
-// replacement occurs. For example if our replacement template is `foo::Bar` and we match some
-// code in the `foo` module, we'll insert just `Bar`.
-//
-// Inherent method calls should generally be written in UFCS form. e.g. `foo::Bar::baz($s, $a)` will
-// match `$s.baz($a)`, provided the method call `baz` resolves to the method `foo::Bar::baz`.
-//
-// The scope of the search / replace will be restricted to the current selection if any, otherwise
-// it will apply to the whole workspace.
-//
-// Placeholders may be given constraints by writing them as `${<name>:<constraint1>:<constraint2>...}`.
-//
-// Supported constraints:
-//
-// |===
-// | Constraint    | Restricts placeholder
-//
-// | kind(literal) | Is a literal (e.g. `42` or `"forty two"`)
-// | not(a)        | Negates the constraint `a`
-// |===
-//
-// Available via the command `rust-analyzer.ssr`.
-//
-// ```rust
-// // Using structural search replace command [foo($a, $b) ==>> ($a).foo($b)]
-//
-// // BEFORE
-// String::from(foo(y + 5, z))
-//
-// // AFTER
-// String::from((y + 5).foo(z))
-// ```
