Struct re_query::EntityView

pub struct EntityView<Primary: Component> { /* private fields */ }

A view of an entity at a particular point in time returned by crate::get_component_with_instances

EntityView has a special primary Component which determines the length of an entity batch. When iterating over individual components, they will be implicitly joined onto the primary component using instance keys.

Implementations

impl<Primary> EntityView<Primary>where Primary: Component,

pub fn num_instances(&self) -> usize

pub fn row_id(&self) -> RowId

impl<Primary: SerializableComponent + DeserializableComponent> EntityView<Primary>where for<'a> &'a Primary::ArrayType: IntoIterator,

pub fn iter_instance_keys( &self ) -> Result<impl Iterator<Item = InstanceKey> + '_>

Iterate over the instance keys

pub fn iter_primary(&self) -> Result<impl Iterator<Item = Option<Primary>> + '_>

Iterate over the primary component values.

pub fn iter_primary_flattened(&self) -> impl Iterator<Item = Primary> + '_

Iterate over the flattened list of primary component values if any.

pub fn has_component<C: Component>(&self) -> bool

Check if the entity has a component and its not empty

pub fn iter_component<C: DeserializableComponent + Clone>( &self ) -> Result<impl Iterator<Item = Option<C>> + '_>where for<'b> &'b C::ArrayType: IntoIterator,

Iterate over the values of a Component.

Always produces an iterator of length self.primary.len()
