(fun)

function declarations

(fun name? args?)

Where:

1. name: function name *
2. args: parameters supplied to the function *

Matching:

1. functions, e.g. fn foo() {}
2. async functions, e.g. async fn foo() {}

Behavior

• Matches function declarations, not closures.

Examples

Find entry-point functions across a crate.

(fun (id main))

Selects in lines { 1 } but not in { 2 }:

fn main() {}
fn main_loop() {}

---

Find functions that expect a ctx parameter first.

(fun _ (arg 1 (id ctx)))

Selects in lines { 1 } but not in { 2 }:

fn handle(ctx: &Context, req: Request) {}
fn render(req: Request) {}
