E0308E0308 — Mismatched Types
The expected type does not match the actual type provided.
rustcargo
Xem chi tiết panic-integer-overflowThe program panicked because an arithmetic operation caused integer overflow in debug mode.
In debug mode, Rust checks for integer overflow on arithmetic operations. Adding, subtracting, or multiplying integers can exceed the type's maximum or minimum value. In release mode, this wraps silently.
Use checked_add(), checked_sub(), or checked_mul() for safe arithmetic. Use wrapping_* or saturating_* methods if wrapping/clamping is desired. Use a larger integer type if the values can grow beyond the current type's range.
E0308The expected type does not match the actual type provided.
clippy::let_and_returnA variable is declared and immediately returned on the next line.
clippy::map_unwrap_orUsing .map().unwrap_or() can be replaced with .map_or().
E0728The .await keyword is used in a function that is not declared async.
E0658A feature that is not yet stabilized in Rust is being used without the feature gate.
