We learnt about vectors Vec and how we can define and initialize a vector. We also saw how we can use ::with_capacity(5) in order to define a Vector which can reside on a stack memory.
We learnt about usize which basically is nothing but the bit-size of your system. If you compile the Rust code on a 32-bit system then the usize would be 32 bits otherwise if you compile the Rust code on a 64-bit system then the usize would be 64 bits. You’d hardly find a system now a days which is lower than 32 bits.
We learnt about the stack memory and how the program uses it to fetch and store variables passed along the function calls during the lifecycle of the program.
We also learnt about the heap memory and how the Rust program uses it to fetch and store dynamic length variables like Vectors.
