E0308E0308 — Mismatched Types
The expected type does not match the actual type provided.
E0597A reference outlives the data it points to.
The borrowed value is dropped (deallocated) while a reference to it still exists. This commonly happens when returning references to local variables or when a borrow scope extends beyond the data's lifetime.
Move the data to an outer scope or return owned data instead of references. Use String instead of &str when returning from functions. Extend the lifetime of the borrowed value to match the reference's lifetime.
E0308The expected type does not match the actual type provided.
E0200An unsafe trait must be implemented with an unsafe impl block.
E0063A struct is being constructed without all required fields.
panic-stack-overflowThe program panicked due to excessive stack usage, typically from deep recursion.
E0502A value cannot be mutably borrowed while an immutable borrow is still active.
E0658A feature that is not yet stabilized in Rust is being used without the feature gate.
