error[E0425]: cannot find value `y` in this scope
  --> $DIR/error-festival.rs:14:5
   |
LL |     y = 2;
   |     ^ help: a local variable with a similar name exists: `x`

error[E0603]: constant `FOO` is private
  --> $DIR/error-festival.rs:22:10
   |
LL |     foo::FOO;
   |          ^^^ this constant is private

note: the constant `FOO` is defined here
  --> $DIR/error-festival.rs:7:5
   |
LL |     const FOO: u32 = 0;
   |     ^^^^^^^^^^^^^^^^^^^

error[E0368]: binary assignment operation `+=` cannot be applied to type `&str`
  --> $DIR/error-festival.rs:12:5
   |
LL |     x += 2;
   |     -^^^^^
   |     |
   |     cannot use `+=` on type `&str`
   |
   = note: an implementation of `std::ops::AddAssign` might be missing for `&str`

error[E0599]: no method named `z` found for reference `&str` in the current scope
  --> $DIR/error-festival.rs:16:7
   |
LL |     x.z();
   |       ^ method not found in `&str`

error[E0600]: cannot apply unary operator `!` to type `Question`
  --> $DIR/error-festival.rs:19:5
   |
LL |     !Question::Yes;

error[E0604]: only `u8` can be cast as `char`, not `u32`
  --> $DIR/error-festival.rs:25:5
   |
LL |     0u32 as char;
   |     ^^^^^^^^^^^^

error[E0605]: non-primitive cast: `u8` as `std::vec::Vec<u8>`
  --> $DIR/error-festival.rs:29:5
   |
LL |     x as Vec<u8>;
   |     ^^^^^^^^^^^^
   |
   = note: an `as` expression can only be used to convert between primitive types. Consider using the `From` trait

error[E0054]: cannot cast as `bool`

   |
LL |     let x_is_nonzero = x as bool;
   |                        ^^^^^^^^^ help: compare with zero instead: `x != 0`

error[E0606]: casting `&u8` as `u32` is invalid
  --> $DIR/error-festival.rs:37:18
