Borrowed Value Does Not Live Long Enough Closure

Rust: Understanding the "Borrowed Value Does Not Live Long Enough" Error

Meaning of the Error

When the compiler informs you that the borrowed value "does not live long enough," it implies that the value's lifetime extends beyond its intended scope.

Resolving the Error

First Use: Pagination works because you transfer ownership of the borrowed value in the first usage.

Second Use: To address the error in the second use, similarly move ownership of the borrowed value.

Loop Optimization: Pass stdioCursorNewContents to DecoderNew within the loop, avoiding multiple file openings and ensuring that the contents reside in the memory.

Assigning Ownership: There's no direct way to specify which variables to move versus borrow into a closure. However, you can employ a technique where you create a data structure and then assign specific variables to be moved and borrowed.
