Struct re_space_view_dataframe::expanded_rows::ExpandedRowsCache

pub(crate) struct ExpandedRowsCache {
    expanded_rows: BTreeMap<u64, u64>,
    valid_for: Id,
}

Storage for ExpandedRows, which should be persisted across frames.

Note: each view should store its own cache. Using a re_viewer_context::SpaceViewState is a good way to do this.

Fields

expanded_rows: BTreeMap<u64, u64>

Maps “table row number” to “additional lines”.

When expanded, the base space is still used for the summary, while the additional lines are used for instances.

valid_for: Id

ID used to invalidate the cache.

Implementations

impl ExpandedRowsCache

fn validate_id(&mut self, id: Id)

This sets the query used for cache invalidation.

If the query doesn’t match the cached one, the state will be reset.
