Enum Error

pub enum Error<Q>
where
    Q: PartialEq + Eq + Clone + Display + Debug + Hash + Ord,
{
    NonUniqueKey(Q),
    NonexistentNode(Q),
}

The errors that can occur when interacting with a Tree.

Variants

NonUniqueKey(Q)

Occurs when an attempt is made to insert a Node at a key which is already in use in the given Tree.

NonexistentNode(Q)

Occurs when an attempt is made to fetch a Node at a key which is not in use in the given Tree.

Trait Implementations

impl<Q> Debug for Error<Q>

where Q: PartialEq + Eq + Clone + Display + Debug + Hash + Ord + Debug,

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<Q> Display for Error<Q>

where Q: PartialEq + Eq + Clone + Display + Debug + Hash + Ord,

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<Q> Error for Error<Q>

where Q: PartialEq + Eq + Clone + Display + Debug + Hash + Ord,

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

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

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.
