Struct Notes 

pub struct Notes<'a> {
    pub group: &'a dyn Fn(&Group) -> Option<String>,
    pub node: &'a dyn Fn(NodeIdx) -> Option<String>,
}

2026-10-02: What a rendering adds to a plan: compute=<group> on each group line (the compute unit its kernels run on, venn::compute), and under it one line per member node (its pipeline, crate::pipeline).

Fields

group: &'a dyn Fn(&Group) -> Option<String>

2026-10-02: The group line’s compute= value, where it answers.

node: &'a dyn Fn(NodeIdx) -> Option<String>

2026-10-02: A member node’s line, where it answers.
