(id)

identifier references

(id val?)

Where:

1. val: identifier name to match *

Behavior

• Bare (id) matches identifier usages, not definition names.
• With a value, it can also match type names, field names, and the final segment of a path::name.

Examples

Find usages of a constant without matching its declaration.

(id CONFIG_PATH)

Selects in lines { 1, 1 } but not in { 1 }:

const CONFIG_PATH: &str = "/etc/app.conf";

fn load() {
  let path = CONFIG_PATH;
  println!("{path}");
}

---

Locate Duration references in type annotations and paths.

(id Duration)

Selects in lines { 1, 1 } but not in { 3 }:

use std::time::Duration;

fn retry(delay: Duration) {
  let _ = Duration::from_secs(1);
}
