Trait Implementations

impl Clone for NullHandle

fn clone(&self) -> NullHandle

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NullHandle

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

Formats the value using the given formatter.

impl Hash for NullHandle

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 NonTerminalHandle for NullHandle

type View = NullView

The type of the view for this non-terminal.

fn node_id(&self) -> CstNodeId

Node ID of the non-terminal.

fn new_with_visit<F, E>( index: CstNodeId, tree: &F, visit_ignored: &mut impl BuiltinTerminalVisitor<E, F>, ) -> Result<NullHandle, ViewConstructionError<TerminalKind, NonTerminalKind, E>>

where F: CstFacade,

fn kind(&self) -> NonTerminalKind

Get the kind of the non-terminal.

fn get_view_with_visit<'v, F, V, O, E>( &self, tree: &F, visit: impl FnMut(<NullHandle as NonTerminalHandle>::View, &'v mut V) -> (O, &'v mut V), visit_ignored: &'v mut V, ) -> Result<O, ViewConstructionError<TerminalKind, NonTerminalKind, E>>

where F: CstFacade, V: BuiltinTerminalVisitor<E, F>,

Get the view of the non-terminal.

fn new<F>( index: CstNodeId, tree: &F, ) -> Result<Self, ViewConstructionError<TerminalKind, NonTerminalKind>>

where F: CstFacade,

Create a new non-terminal handle from a node.

fn get_view<C>( &self, tree: &C, ) -> Result<Self::View, ViewConstructionError<TerminalKind, NonTerminalKind>>

where C: CstFacade,

Get the view of the non-terminal.

impl Ord for NullHandle

fn cmp(&self, other: &NullHandle) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for NullHandle

fn eq(&self, other: &NullHandle) -> 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 PartialOrd for NullHandle

fn partial_cmp(&self, other: &NullHandle) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
