+A lifetime indication has not been added to specify the span of your type.
+
+Erroneous code example:
+
+```rust
-```rust
+```compile_fail,E0726
-```rust
+```compile_fail,E0726
+struct Abc<'a> {
+    title: &'a str,
+}
+
+struct SomeStruct;
+
+impl SomeStruct {
+    pub fn some_fn(&self, abc: Abc) { // error: implicit elided lifetime not allowed here rustc(E0726)
+        // ...
+    } 
+}
+```
+
+Specify the lifetime of struct `Abc` or indicate the anonymous lifetime like `abc: Abc<'_>`.
