Struct QueryLens 

pub struct QueryLens<'w, Q, F = ()>
where
    Q: QueryData,
    F: QueryFilter,
{ /* private fields */ }

Type returned from Query::transmute_lens containing the new QueryState.

Call query or into to construct the resulting Query

Implementations

impl<'w, Q, F> QueryLens<'w, Q, F>

where Q: QueryData, F: QueryFilter,

pub fn query(&mut self) -> Query<'_, '_, Q, F>

Create a Query from the underlying QueryState.

impl<'w, Q, F> QueryLens<'w, Q, F>

where Q: ReadOnlyQueryData, F: QueryFilter,

pub fn query_inner(&self) -> Query<'w, '_, Q, F>

Create a Query from the underlying QueryState. This returns results with the actual “inner” world lifetime, so it may only be used with read-only queries to prevent mutable aliasing.

Trait Implementations

impl<'w, 'q, Q, F> From<&'q mut Query<'w, '_, Q, F>> for QueryLens<'q, Q, F>

where Q: QueryData, F: QueryFilter,

fn from(value: &'q mut Query<'w, '_, Q, F>) -> QueryLens<'q, Q, F>

Converts to this type from the input type.

impl<'w, 's, Q, F> From<&'s mut QueryLens<'w, Q, F>> for Query<'s, 's, Q, F>

where Q: QueryData, F: QueryFilter,

fn from(value: &'s mut QueryLens<'w, Q, F>) -> Query<'s, 's, Q, F>

Converts to this type from the input type.
