--> $DIR/reassignment_immutable_fields_twice.rs:7:5

LL | x.0 = 1;
| ^^^^^^^ cannot assign

help: consider changing this to be mutable

error[E0381]: partially assigned binding `x` isn't fully initialized
--> $DIR/reassignment_immutable_fields_twice.rs:12:5

LL | let x: (u32, u32);
| - binding declared here but left uninitialized
LL | x.0 = 1;
| ^^^^^^^ `x` partially assigned here but it isn't fully initialized

= help: partial initialization isn't supported, fully initialize the binding with a default value and mutate it, or use `std::mem::MaybeUninit`
error: aborting due to 2 previous errors
