Struct View 

pub struct View<R>(/* private fields */);

A wrapper for a Lookup implementation

Implementations

impl<R> View<R>

pub fn new(retriever: R) -> Self

Trait Implementations

impl<R> Deref for View<R>

where R: Deref,

type Target = <R as Deref>::Target

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<P> Positions for View<P>

where P: Positions,

type Pos = <P as Positions>::Pos

fn positions(&self) -> impl Iterator<Item = &Self::Pos>

Returns all knwon positions as an iterator.

impl<R, Q> Retriever<Q> for View<R>

where R: Retriever<Q>,

type Pos = <R as Retriever<Q>>::Pos

fn key_exist(&self, key: Q) -> bool

Check, that the given key exist.

fn pos_by_key(&self, key: Q) -> &[Self::Pos]

Returns all known positions for a given Key. If the Key not exist, than is the slice empty.

fn pos_by_many_keys<'a, K>( &'a self, keys: K, ) -> impl Iterator<Item = &'a Self::Pos>

where K: IntoIterator<Item = Q>, Self::Pos: 'a,

Returns all known positions for a given iterator of Keys.
