Struct re_space_view::HybridLatestAtResults

pub struct HybridLatestAtResults<'a> {
    pub overrides: LatestAtResults,
    pub results: LatestAtResults,
    pub defaults: LatestAtResults,
    pub ctx: &'a ViewContext<'a>,
    pub query: LatestAtQuery,
    pub data_result: &'a DataResult,
}

Wrapper that contains the results of a latest-at query with possible overrides.

Although overrides are never temporal, when accessed via the crate::RangeResultsExt trait they will be merged into the results appropriately.

Fields

overrides: LatestAtResults

results: LatestAtResults

defaults: LatestAtResults

ctx: &'a ViewContext<'a>

query: LatestAtQuery

data_result: &'a DataResult

Implementations

impl<'a> HybridLatestAtResults<'a>

pub fn get( &self, component_name: impl Into<ComponentName> ) -> Option<&UnitChunkShared>

Returns the UnitChunkShared for the specified re_types_core::Component.

pub fn fallback_raw(&self, component_name: ComponentName) -> Box<dyn ArrowArray>

pub fn get_required_mono<C: Component>(&self) -> Option<C>

Utility for retrieving the first instance of a component, ignoring defaults.

pub fn get_mono<C: Component>(&self) -> Option<C>

Utility for retrieving the first instance of a component.

pub fn get_mono_with_fallback<C: Component + Default>(&self) -> C

Utility for retrieving the first instance of a component.

pub fn get_required_instance<C: Component>(&self, index: usize) -> Option<C>

Utility for retrieving a single instance of a component, not checking for defaults.

If overrides or defaults are present, they will only be used respectively if they have a component at the specified index.

pub fn get_instance<C: Component>(&self, index: usize) -> Option<C>

Utility for retrieving a single instance of a component.

If overrides or defaults are present, they will only be used respectively if they have a component at the specified index.

pub fn get_instance_with_fallback<C: Component + Default>( &self, index: usize ) -> C

Utility for retrieving a single instance of a component.

If overrides or defaults are present, they will only be used respectively if they have a component at the specified index.

Trait Implementations

impl<'a> RangeResultsExt for HybridLatestAtResults<'a>

fn get_required_chunks( &self, component_name: &ComponentName ) -> Option<Cow<'_, [Chunk]>>

Returns component data for the given component, ignores default data if the result distinguishes them.

fn get_optional_chunks( &self, component_name: &ComponentName ) -> Cow<'_, [Chunk]>

Returns component data for the given component or an empty array.

fn iter_as( &self, timeline: Timeline, component_name: ComponentName ) -> HybridResultsChunkIter<'_>

Returns a zero-copy iterator over all the results for the given (timeline, component) pair.
