Cannot Borrow Data in a Reference as Mutable

Error in Rust Programming Language

Issue Description

An error message has been encountered when attempting to use the WEB function in Rust. The error reads as "Cannot borrow data in a reference as mutable." This indicates that an attempt is being made to mutate a value that is currently being referenced immutably.

Solution

To resolve this error, it is necessary to ensure that the value being referenced is mutable. One way to achieve this is by using the "mut" keyword when declaring the variable. Additionally, it is important to ensure that the value is not referenced elsewhere in the program in an immutable manner.
