Trait Implementations

impl<T: Send + Sync + 'static> IsQuery for Without<T>

type LockedColumns<'a> = bool

Data that is read or write locked by performing this query.

type ExtensionColumns = ()

Data that can be used to append to columns. Typically vectors of component entries or bundles of vectors of component entries.

type QueryResult<'a> = Either<Repeat<()>, IntoIter<(), Global>>

The iterator that is produced by performing a query on one archetype.

type ParQueryResult<'a> = RepeatN<()>

The parallel iterator that is produced by performing a query on one archetype.

type QueryRow<'a> = ()

The iterator item.

fn borrows() -> Vec<Borrow>

fn lock_columns<'a>(arch: &'a Archetype) -> Self::LockedColumns<'a>

Find and acquire a “lock” on the columns for reading or writing.

fn extend_locked_columns<'a, 'b>(
    _: &'b mut Self::LockedColumns<'a>,
    _: Self::ExtensionColumns,
    _: Option<(&mut Vec<usize>, &mut usize)>
)

Extend entries in the locked columns.

fn iter_mut<'a, 'b>(
    lock: &'b mut Self::LockedColumns<'a>
) -> Self::QueryResult<'b>

Create an iterator over the rows of the given columns.

fn iter_one<'a, 'b>(
    lock: &'b mut Self::LockedColumns<'a>,
    _: usize
) -> Self::QueryResult<'b>

Create an iterator over one row with the given index.

fn par_iter_mut<'a, 'b>(
    len: usize,
    lock: &'b mut Self::LockedColumns<'a>
) -> Self::ParQueryResult<'b>

Create an iterator over the rows of the given columns.
