Fix E0132: #[link] Attribute Missing Name Argument

1. Symptoms

When attempting to link an external library using the #[link] attribute without specifying the required name parameter, the Rust compiler emits error E0132. The error manifests during compilation with a message indicating that the name argument is mandatory for this attribute context.

The typical compiler output looks like this:

error[E0132]: `#[link]` attribute in this context requires a `name` argument
  --> src/main.rs:5:1
   |
5  | #[link(kind = "static", cfg(feature = "openssl"))]
   | ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ help: provide the argument: `name = "..."`
   |
   = note: `#[link]` accepts: `name`, `kind`, `cfg`, `modifiers`, `wasm_import_module`

In this example, the developer attempted to specify kind and cfg parameters but omitted the essential name argument that identifies which library to link. The compiler recognizes the attribute syntax but refuses compilation because the linkage target cannot be determined without a library name.
