What are the best practices for handling errors in Rust?
In Rust, it's essential to use the Result
and Option
types for error handling. This allows you to explicitly manage errors.
Can you explain the difference between Result
and Option
?
Sure! Result
is used for functions that can return an error, while Option
is for cases where a value might be absent. Result
has two variants: Ok

for failure.
How do I propagate errors in Rust?
You can use the ?

What about logging errors?
Logging errors is crucial for debugging. You can use the log
crate to log errors at different levels, such as error!
