operators, before the expression they apply to.
Rust defines three unary operators. They are all written as prefix operators,

: Negation. May only be applied to numeric types.

: Logical negation. On the boolean type, this flips between `true` and
`false`. On integer types, this inverts the individual bits in the
two's complement representation of the value.
* `box`
: [Boxing](#pointer-types) operators. Allocate a box to hold the value they
are applied to, and store the value in it. `box` creates a box.
* `&`
: Borrow operator. Returns a reference, pointing to its operand. The operand
of a borrow is statically proven to outlive the resulting pointer. If the
borrow-checker cannot prove this, it is a compilation error.
