### Unary operator expressions
Rust defines six symbolic unary operators. They are all written as prefix
operators, before the expression they apply to.
Rust defines three unary operators. They are all written as prefix operators,
before the expression they apply to.
* `-`
: 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.
