    Types

    +
    +

    This is a summary of rust basic knowledge I learned from (Rust the Book)[https://doc.rust-lang.org/book/] chapter 1 ~ chapter 13 +I will use C to compare with since I familiar it.

    +
    +

    There are a bunch of built-in types we can work with: scalar types and compound types. +Those scalar types are just alike as C language. +| scalar types | rust | c | +| ------------- |------------- | ------- | +| integer | i(u)8/i16/i32/i64 | (unsigned) char/short/int/long | +| float | f32/f64 | float/double | +| boolean | true/false | True/False (non-zero/zero) | +| character | char | char |

    +

    The compound types are a bit different. rust provides many hands-on types where C type is not the same or needs to define explicitly.

    + + + + + + +
    compound typerustc
    structsamesame
    enumenum element can be seen as key that could take valuerepresent numberic value, default starting from 0
    arrayvectorarray
    stringa wraper of vectorpointer of char *
    tupleexistno such type in C
    +

    Variable declaration in rust is kinda tricky.

    +

    A normal declare syntax would be like let unmutable_variable = 3. This will imply that variable is i32 type +since the value we assign to is a integer and the default type for integer on most OS is i32. +We can explicit type by using type annotation: let unmutable_variable: u8 = 3. This will make variable +unmutable_variable is u8 type and has 3 as its value. We need to assign a value +to variable if we don't annotate type while declaration, otherwise compiler would prompt error.

    +

    Notice that, declaration as above one won't allow us to change value, if we want to be able to change variable's +value at runtime, we need to explicit it, for security reason:

    +
    let mut mutable_variable = 3;
+println!("first define: {mutable_variable}");
+mutable_variable = 5;
+
+println!("change value to: {mutable_variable}");
+
    +
    +

    println!() is called macro, which would not cover for now.

    +
