Implementations

impl TreeParentId

pub fn is_node(&self) -> bool

Returns true if this is a TreeParentId::Node, otherwise false

pub fn as_node_mut(&mut self) -> Option<&mut TreeID>

Optionally returns mutable references to the inner fields if this is a TreeParentId::Node, otherwise None

pub fn as_node(&self) -> Option<&TreeID>

Optionally returns references to the inner fields if this is a TreeParentId::Node, otherwise None

pub fn into_node(self) -> Result<TreeID, TreeParentId>

Returns the inner fields if this is a TreeParentId::Node, otherwise returns back the enum in the Err case of the result

pub fn is_root(&self) -> bool

Returns true if this is a TreeParentId::Root, otherwise false

pub fn is_deleted(&self) -> bool

Returns true if this is a TreeParentId::Deleted, otherwise false

pub fn is_unexist(&self) -> bool

Returns true if this is a TreeParentId::Unexist, otherwise false

Trait Implementations

impl Clone for TreeParentId

fn clone(&self) -> TreeParentId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TreeParentId

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

Formats the value using the given formatter.

impl From<&TreeID> for TreeParentId

fn from(id: &TreeID) -> TreeParentId

Converts to this type from the input type.

impl From<Option<TreeID>> for TreeParentId

fn from(id: Option<TreeID>) -> TreeParentId

Converts to this type from the input type.

impl From<TreeID> for TreeParentId

fn from(id: TreeID) -> TreeParentId

Converts to this type from the input type.

impl Hash for TreeParentId

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for TreeParentId

fn eq(&self, other: &TreeParentId) -> 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.

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
