pub struct QueryMut<'q, Q>where
    Q: Query,{ /* private fields */ }
Expand description

A query builder that’s convertible directly into an iterator

Implementations§

§

impl<'q, Q> QueryMut<'q, Q>where Q: Query,

pub fn view(&mut self) -> View<'_, Q>

Provide random access to the query results

pub fn with<R>(self) -> QueryMut<'q, With<Q, R>>where R: Query,

Transform the query into one that requires another query be satisfied

See QueryBorrow::with

pub fn without<R>(self) -> QueryMut<'q, Without<Q, R>>where R: Query,

Transform the query into one that skips entities satisfying another

See QueryBorrow::without

pub fn into_iter_batched(self, batch_size: u32) -> BatchedIter<'q, Q>

Like into_iter, but returns child iterators of at most batch_size elements

Useful for distributing work over a threadpool.
