Assignment statement

^Syntax
AssignmentStatement :
   Expression = Expression

An assignment statement moves a value into a specified place. An assignment statement consists of an expression that holds a mutable place, followed by an equals sign (=) and a value expression.

Example:

contract Foo {
  some_array: Array<u256, 10>


  pub fn bar(mut self) {
    let mut val1: u256 = 10
    // Assignment of stack variable
    val1 = 10

    let mut values: (u256, u256) = (1, 2)
    // Assignment of tuple item
    values.item0 = 3

    // Assignment of storage array slot
    self.some_array[5] = 1000
  }
}
