Implementations

impl Index

pub fn is_key(&self) -> bool

Returns true if this is a Index::Key, otherwise false

pub fn as_key_mut(&mut self) -> Option<&mut InternalString>

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

pub fn as_key(&self) -> Option<&InternalString>

Optionally returns references to the inner fields if this is a Index::Key, otherwise None

pub fn into_key(self) -> Result<InternalString, Index>

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

pub fn is_seq(&self) -> bool

Returns true if this is a Index::Seq, otherwise false

pub fn as_seq_mut(&mut self) -> Option<&mut usize>

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

pub fn as_seq(&self) -> Option<&usize>

Optionally returns references to the inner fields if this is a Index::Seq, otherwise None

pub fn into_seq(self) -> Result<usize, Index>

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

pub fn is_node(&self) -> bool

Returns true if this is a Index::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 Index::Node, otherwise None

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

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

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

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

Trait Implementations

impl Clone for Index

fn clone(&self) -> Index

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Index

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Index

fn deserialize<__D>( __deserializer: __D, ) -> Result<Index, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Index

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

Formats the value using the given formatter.

impl From<usize> for Index

fn from(s: usize) -> Index

Converts to this type from the input type.

impl PartialEq for Index

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

impl Serialize for Index

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.

impl TryFrom<&str> for Index

type Error = &'static str

The type returned in the event of a conversion error.

fn try_from(s: &str) -> Result<Index, &'static str>

Performs the conversion.

impl Eq for Index

impl StructuralPartialEq for Index
