Enum MutationStage 

pub enum MutationStage {
    Update {
        target: BindingId,
        data: UpdateData,
    },
    Delete {
        target: BindingId,
        detach: DetachMode,
    },
    Insert(InsertStage),
}

One write stage applied to the binding table, in textual order.

A stage consumes the binding rows produced by earlier steps (or a single empty row, for a leading INSERT), performs its write through the native document pipeline, and passes the rows on so a trailing RETURN can project the post-mutation state.

Variants

Update

SET a.p = v / SET a = {…} / REMOVE a.p: mutate the record bound at target.

Fields

target: BindingId

data: UpdateData

Delete

[DETACH|NODETACH] DELETE a: delete the record bound at target.

Fields

target: BindingId

detach: DetachMode

Insert(InsertStage)

INSERT …: create the new nodes and relate the new edges.
