Run with error

[lijobs]

When I tried to operate this order here, the system said that I run with the error as follows:

cargo run --release --bin toysql the following packages contain code that will be rejected by a future version of Rust: nom v5.1.2 note: to see what the problems were, use the option --future-incompat-report, or run cargo report future-incompatibilities --id 1 Running target/release/toysql Error: Internal("Connection refused (os error 111)")

My operation system is Ubuntu22.04 and the rust version is 1.70. Please help me to solve this issue. Thanks!
