Understanding Lifetime Annotations in Struct Definitions in Rust

In Rust, the concept of lifetimes ensures that all borrows are valid, preventing references from becoming invalid or pointing to memory that no longer exists. When we define a struct that holds references, we need to specify the lifetime of the reference using lifetime annotations. Lifetime annotations describe the relationships between the lifetimes of multiple references to ensure that references remain valid for the duration they are used. When a struct holds a reference, it must declare a lifetime parameter, which is the scope for which that reference is valid.
