Enum Mode 

pub enum Mode {
    Normal,
    Choosing {
        path: Vec<Seg>,
        choices: Vec<Choice>,
        selected: usize,
        filter: String,
    },
    Editing {
        buffer: String,
        path: Vec<Seg>,
        slot: EditSlot,
    },
}

Interaction mode: normal navigation, or editing one text field of a node.

Variants

Normal

Choosing

Picking a value off a list rather than typing one (Model::begin_choose).

A mode of its own rather than an editor seeded with a list, because the two take different keys: everything printable is a filter here and a value there, and Enter commits a row rather than a buffer.

Fields

path: Vec<Seg>

The node being chosen for.

choices: Vec<Choice>

Everything on offer, unfiltered and in the order it was offered.

selected: usize

Which of the filtered choices the cursor is on — see Model::visible_choices.

filter: String

What has been typed to narrow the list.

Editing

Fields

buffer: String

path: Vec<Seg>

The node being edited. Held here rather than re-read from the selection on commit, so an edit belongs to a node and not to whichever list the cursor happens to be in — the two projections index differently, and a commit must not care which one opened it.

slot: EditSlot

Which of the node’s texts the buffer holds.
