Struct re_types::blueprint::archetypes::SpaceViewContents

pub struct SpaceViewContents {
    pub query: Vec<QueryExpression>,
}

Archetype: The contents of a SpaceView.

The contents are found by combining a collection of QueryExpressions.

+ /world/**           # add everything…
- /world/roads/**     # …but remove all roads…
+ /world/roads/main   # …but show main road

If there is multiple matching rules, the most specific rule wins. If there are multiple rules of the same specificity, the last one wins. If no rules match, the path is excluded.

Specifying a path without a + or - prefix is equivalent to +:

/world/**           # add everything…
- /world/roads/**   # …but remove all roads…
/world/roads/main   # …but show main road

The /** suffix matches the whole subtree, i.e. self and any child, recursively (/world/** matches both /world and /world/car/driver). Other uses of * are not (yet) supported.

Internally, EntityPathFilter sorts the rule by entity path, with recursive coming before non-recursive. This means the last matching rule is also the most specific one. For instance:

+ /world/**
- /world
- /world/car/**
+ /world/car/driver

The last rule matching /world/car/driver is + /world/car/driver, so it is included. The last rule matching /world/car/hood is - /world/car/**, so it is excluded. The last rule matching /world is - /world, so it is excluded. The last rule matching /world/house is + /world/**, so it is included.

Fields

query: Vec<QueryExpression>

The QueryExpression that populates the contents for the SpaceView.

They determine which entities are part of the spaceview.
