@ -471,11 +471,11 @@ The comparison operators are the traditional `==`, `!=`, `<`, `>`,
|

`<=`, and `>=`. Short-circuiting (lazy) boolean operators are written
|

`&&` (and) and `||` (or).

For type casting, Rust uses the binary `as` operator, which has a
|
||||
precedence between the bitwise combination operators (`&`, `|`, `^`)
|
||||
and the comparison operators. It takes an expression on the left side,
|
||||
and a type on the right side, and will, if a meaningful conversion
|
||||
exists, convert the result of the expression to the given type.
