108#### Structural Seach and Replace
109
110Search and replace with named wildcards that will match any expression.
111The syntax for a structural search replace command is `<search_pattern> ==>> <replace_pattern>`. A `$<name>:expr` placeholder in the search pattern will match any expression and `$<name>` will reference it in the replacement. Available via the command `rust-analyzer.ssr`.
112
113```rust
114// Using structural search replace command [foo($a:expr, $b:expr) ==>> ($a).foo($b)]
115
116// BEFORE
117String::from(foo(y + 5, z))
118
119// AFTER
120String::from((y + 5).foo(z))
