Trait Implementations

impl<R> Clone for WithItem<R>

where R: Clone,

fn clone(&self) -> WithItem<R>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<R> Debug for WithItem<R>

where R: Debug,

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

Formats the value using the given formatter.

impl<T, U> Foldable<T, U> for WithItem<T>

type Mapped = WithItem<U>

fn fold<F>( self, folder: &mut F, ) -> Result<<WithItem<T> as Foldable<T, U>>::Mapped, <F as Fold<T>>::Error>

where F: Fold<T, TargetU = U> + ?Sized,

impl<R> Node for WithItem<R>

const NAME: &'static str = "withitem"

const FIELD_NAMES: &'static [&'static str]

impl<R> PartialEq for WithItem<R>

where R: PartialEq,

fn eq(&self, other: &WithItem<R>) -> 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.
