Enum id_tree::NodeIdError

pub enum NodeIdError {
    InvalidNodeIdForTree,
    NodeIdNoLongerValid,
}

Enum for all of the possible NodeId errors that could occur.

Variants

InvalidNodeIdForTree

Occurs when a NodeId is used on a Tree from which it did not originate.

NodeIdNoLongerValid

Occurs when a NodeId is used on a Tree after the corresponding Node has been removed.

impl Eq for NodeIdError

impl Error for NodeIdError

fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

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

The lower-level source of this error, if any.

pub fn backtrace(&self) -> Option<&Backtrace>

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

Returns a stack backtrace, if available, of where this error occurred.

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

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

impl PartialEq<NodeIdError> for NodeIdError

fn eq(&self, other: &NodeIdError) -> bool

This method tests for self and other values to be equal, and is used by ==.

#[must_use]pub fn ne(&self, other: &Rhs) -> bool

This method tests for !=.
