Struct double_map::InsertError

pub struct InsertError<K1, K2, V> {
    pub error: ErrorKind,
    pub keys: (K1, K2),
    pub value: V,
}

The error returned by insert method (and also try_insert method) when there is no way to distinguish how given value with key #1 and key #2 should be inserted. It is also part of the TryInsertError enum which if returned by try_insert method of DHashMap. For more information about error kinds look to ErrorKind enum.

Contains the ErrorKind enum, the provided keys and value that were not inserted. These returned keys and value can be used for another purpose.
