Enum ControlFlowKind 

pub enum ControlFlowKind {
    ForEach {
        item_name: String,
        key_path: Option<String>,
    },
    Conditional,
    Router {
        cache: IndexMap<String, Vec<NodeId>>,
        current_route_key: Option<String>,
        max_cache_size: usize,
    },
}

The kind of control flow node for re-reconciliation

Variants

ForEach

ForEach iteration container

Fields

item_name: String

key_path: Option<String>

Conditional

Conditional (When/If) container

Router

Router container — selects which Route’s children to render based on the current location.

Retains detached route subtrees between navigations so that navigating back to a previously-visited route emits Attach patches instead of rebuilding the tree. The cache is an insertion-ordered LRU; inserting past max_cache_size evicts the oldest entry and tears down its subtree.

Fields

cache: IndexMap<String, Vec<NodeId>>

Detached top-level child NodeIds keyed by route pattern. Each entry corresponds to a route that was previously rendered and has since been unlinked from the Router’s children; descendants of these NodeIds stay in the InstanceTree + DependencyGraph (so state updates still flow through them — keep-alive semantics).

current_route_key: Option<String>

Route pattern of the currently-rendered route, if any. None when no route matches (fallback rendered, or on brand-new Router before first location resolution).

max_cache_size: usize

Maximum number of routes to cache before LRU eviction.
