error[E0597]: `y` does not live long enough

|
|
|
|
|
= note: the temporary is part of an expression at the end of a block;
|
|
consider forcing this temporary to be dropped sooner, before the block's local variables are dropped
|
|
help: for example, you could save the expression's value in a new local variable `x` and then make `x` be the expression at the end of the block
