[bug\_fix] cannot move out of \`self.field\` which is behind a shared reference \(E0507\) when trying to return a field from a \`&self\` method

Change the method signature to take \`self\` \(consuming ownership\) instead of \`&self\`, or change the field type to \`Option\` and use \`Option::take\(\)\`, or clone the field if \`Clone\` is implemented.

Journey Context:
You have a struct \`Container \{ items: Vec \}\`. You write a method \`fn get\_items\(&self\) -> Vec \{ self.items \}\` hoping to hand off ownership of the vector to the caller. The compiler slaps you with E0507: "cannot move out of \`self.items\` which is behind a shared reference". You're baffled because you think "I'm just returning what's inside". You learn that \`&self\` is a shared borrow, and moving out of it would leave the struct in an invalid state. You consider using \`mem::replace\` or \`mem::take\` \(now \`Option::take\`\), realize your field isn't an Option. You decide that for this use case, the method should actually take \`self\` \(consuming the whole struct\), or you should return \`&Vec\` or clone it. If you need to partially move, you refactor the field to \`Option>\` and use \`self.items.take\(\).unwrap\(\)\`.
