pub fn not(e: impl IntoExpr) -> ExprExpand description
NOT expr.
The operand is parenthesised if it needs it, the result is not — matching bob,
where Not is the one builder method that does not wrap its own output. It
does not need to: NOT binds looser than anything it can contain, so
NOT ("a" = $1) is already unambiguous, and an enclosing operator will
parenthesise it if one comes along.
