Struct CoarseGrainedNode 

pub struct CoarseGrainedNode {
    pub path: String,
    pub marker_offset: Option<usize>,
    pub relations: Vec<String>,
    pub cost: PlanCost,
    pub children: Vec<ChildEntry>,
}

One node of the coarse-grained tree — the REPL text formatter and the Query Editor’s visual view both render this same shape directly (see the crate’s analyze design notes).

Fields

path: String

marker_offset: Option<usize>

Source byte offset to plant this path’s analyze marker at in the echoed query text (see ShapePathAlias::marker_offset) — the REPL text formatter’s only use for it; the Query Editor’s visual view has no echoed query text to mark up, so it just ignores this field.

relations: Vec<String>

Relation names touched by this path’s own plan nodes (not those of a nested child path) — deduplicated, in first-encountered order.

cost: PlanCost

children: Vec<ChildEntry>
