Enum TryInsertError 

pub enum TryInsertError<'a, K1: 'a, K2: 'a, V: 'a> {
    Occupied(OccupiedError<'a, K1, K2, V>),
    Insert(InsertError<K1, K2, V>),
}

The error returned by try_insert method when the keys already exist and point to the same value (look at OccupiedError) or there is no way to distinguish how given value with key #1 and key #2 should be inserted. For more information about error kinds look at OccupiedError, InsertError structures and ErrorKind enum.

Depending of error kind, this enum can contain:

• When there is TryInsertError::Occupied variant, it contains the occupied entry, and the value that was not inserted (through OccupiedError structure).
• When there is TryInsertError::Insert variant, it contains the ErrorKind enum, the provided keys and value that were not inserted (through InsertError structure).

Variants

Occupied(OccupiedError<'a, K1, K2, V>)

The error kind returned by try_insert when the keys already exist and point to the same value. Contains the OccupiedError structure.

Insert(InsertError<K1, K2, V>)

The error kind returned by try_insert method when there is no way to distinguish how given value with key #1 and key #2 should be inserted. For more information about error kinds look at InsertError structure and ErrorKind enum.

Contains the InsertError structure.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting
