Why does this happen?

breaks.rs

struct Record {
    name: String,
    message: String,
}

// Let's say `record` is an instance of Record, with strings in name and message.


// This will work correctly:
let message =
    if some_condition {
        record.name.as_slice()
    } else {
        record.message.as_slice()
    };
    

// This will break, saying error: cannot move out of dereference of `&`-pointer.
let message =
    if some_condition {
        record.name
    } else {
        record.message
    };

// This is how i create the records
let mut records: Vec<Record> = vec![];                                      
for record in reader.decode() {                                             
    let record: Record = record.unwrap();                                   
    records.push(record);                                                   
}
