Trait Implementations

impl Clone for OptionTreeViewNode

fn clone(&self) -> OptionTreeViewNode

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for OptionTreeViewNode

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

Formats the value using the given formatter.

impl Default for OptionTreeViewNode

fn default() -> OptionTreeViewNode

Returns the “default value” for a type.

impl From<Option<TreeViewNode>> for OptionTreeViewNode

fn from(o: Option<TreeViewNode>) -> OptionTreeViewNode

Converts to this type from the input type.

impl From<OptionTreeViewNode> for Option<TreeViewNode>

fn from(o: OptionTreeViewNode) -> Option<TreeViewNode>

Converts to this type from the input type.

impl PartialEq for OptionTreeViewNode

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

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
