“Mace Windu, you were lucky to escape,” says Boba trying to sound tough. We next see that a holocommunication sent to the Jedi Council, where Boba Fett is holding the three hostages in front of him on their knees, while he is pointing a blaster at the back of their heads. It also shows, once again, that Fett is insecure about his identity in relationship to the clone troopers. This interaction shows a young Boba Fett who is, on the one hand, compassionate, and trying to show his being reasonable and, on the other hand, trying to show that he is tough, lest he be considered weak. I’m no clone – not like those two,” pointing to two clone troopers. I can tell.” To which Boba immediately responds, trying to seem tough: “What do you know, old man?” Again, Killian observes: “I know a good soldier when I see one.” Boba tries to distinguish himself: “I’m no soldier. “You don’t have to do this,” observes Admiral Killian. Boba Fett giving Admiral Killian water to drink while talking with himĪt the outset, while on the bridge of Slave I, Boba decides to talk to the hostages they took from the crash of the “Endurance”. Boba says to Admiral Killian, who is being held hostage: “This isn’t what I wanted,” removing the kerchief from his mouth, compassionately, then giving him water to drink. In the first half of the second season finale, “Lethal Trackdown”, portrays a young Boba Fett, in which he is incredibly hesitant to killing anybody who is not Mace Windu. a subtrait might make its supertrait's methods' impls more specialized, faster, use less memory, e.g.Was Boba Fett always a tough fighter, willing to kill at a moment’s notice? An episode of “Star Wars: The Clone Wars” shows us a young Boba Fett who is not interested in killing innocents."Refinement" is intentionally kept somewhat vague because it can mean different things in different contexts: In my opinion, the most simple and elegant mental model for understanding the relationship between subtraits and supertraits is: subtraits refine their supertraits. The mental model we developed earlier doesn't help us here. The syntax above looks very similar to the syntax for applying a trait bound on a generic type and yet Copy doesn't depend on Clone at all. Before introducing a mental model that neatly encapsulates all of that complexity let's quickly review and establish the mental model we use for understanding trait bounds on generic types: Hopefully the examples above show that the relationship between subtraits and supertraits can be complex. sub_method() // prints "in sub", "in super" super_method() // prints "in super", "in sub" CallEachOther( true). sub_method() // prints "in sub" CallEachOther( true). super_method() // prints "in super", "in sub"ĬallSubFromSuper. sub_method() // prints "in sub", "in super"ĬallSubFromSuper. super_method() // prints "in super"ĬallSuperFromSub. To explain why and how we'd use one let's start by writing an is_even method for number types:ĬallSuperFromSub. Generic Blanket ImplsĪ generic blanket impl is an impl on a generic type instead of a concrete type. Many traits in the standard library provide default impls for many of their methods. greet_loudly( "John")) // prints "¡Hola John!" any type implementing Trait can // choose the type of AssociatedType impl Trait for SomeType ", Hola. Self always refers to the implementing type. Trait items are any items that are part of a trait declaration. We'll cover just enough of the basics so that the rest of the article can be streamlined without having to repeat the same explanations of the same concepts over and over as they reappear in different traits. You can read this article in order section by section or jump around to whichever traits interest you the most because each trait section begins with a list of links to Prerequisite sections that you should read to have adequate context to understand the current section's explanations.
