Line 43:

trait Foo {

fn fa(&self);

fn gb(&self);

}

trait Bar {

fn gb(&self);

}

Line 54:

impl Foo for Qux {

fn fa(&self) { println!("Qux’s implementation of Foo::fa"); }

fn gb(&self) { println!("Qux’s implementation of Foo::gb"); }

}

impl Bar for Qux {

fn g(&self) { println!("Qux’s implementation of Bar::gb"); }

}

fn main() {

let qc = Qux;

// These two are equivalent:

qc.fa();

Foo::fa(&qc);

// This would not work because .gb() is ambiguous:

// qc.gb();

// But it's possible to disambiguate using UFCS

Foo::gb(&qc);

Bar::gb(&qc);

}
