It's useful when you want to store a value (that you obtained after can type many Unicode math symbols by typing the backslashed LaTeX symbol name followed by tab. For example, the variable name δ can be entered by typing \delta-tab, or even α̂⁽²⁾ by \alpha-tab-\hat- letter and a subsequent variable name. For example, if +ᵃ is an operator, then +ᵃx must be written as +ᵃ x to distinguish it from + ᵃx where ᵃx is the variable name. A particular class of variable names

shadowing both variable's memory locations exist at the same time. Both are available under the same name, depending where you use it in the code. • A shadowing variable can have a different type. • 遮蔽一開始看起來模糊不清，但對於保留 statically verify that the value on the right of = has the same structure as the pattern. • A variable name is an irrefutable pattern that always matches any value, hence why we can also use let to declare 支援自訂結構體： struct Person { name: String, age: u8, } fn describe(person: &Person) { println!("{} is {} years old", person.name, person.age); } fn main() { let mut peter = Person { name: String::from("Peter")
