# `Logistiki.VirtualAccounts.VirtualAccountClosure`
[🔗](https://github.com/thanos/logistiki/blob/v0.1.0/lib/logistiki/virtual_accounts/virtual_account_closure.ex#L1)

Closure table for the virtual account hierarchy.

Each row records that `ancestor` is an ancestor of `descendant` at `depth`.
A self-row has depth 0. The closure table is maintained by
`Logistiki.VirtualAccounts` on insert and move.

## Fields

  * `id` — `integer()` — primary key (e.g. `1`)
  * `ancestor_id` — `integer()` — the ancestor account id (e.g. `1` for `ASSETS`)
  * `descendant_id` — `integer()` — the descendant account id (e.g. `4` for `ASSETS:CASH:USD:NOSTRO`)
  * `depth` — `integer()` — 0 for self, 1 for direct child, 2 for grandchild (e.g. `3`)
  * `inserted_at` — `DateTime.t() | nil` — set on insert (no `updated_at`; e.g. `~U[2026-07-07 12:00:00Z]`)

## Example

    %Logistiki.VirtualAccounts.VirtualAccountClosure{
      id: 1,
      ancestor_id: 1,    # ASSETS
      descendant_id: 4,  # ASSETS:CASH:USD:NOSTRO
      depth: 3,
      inserted_at: ~U[2026-07-07 12:00:00Z]
    }

# `t`

```elixir
@type t() :: %Logistiki.VirtualAccounts.VirtualAccountClosure{
  __meta__: term(),
  ancestor_id: integer() | nil,
  depth: integer() | nil,
  descendant_id: integer() | nil,
  id: integer() | nil,
  inserted_at: DateTime.t() | nil
}
```

The `VirtualAccountClosure` struct type.

A row in the closure table recording that `ancestor_id` is an ancestor of
`descendant_id` at the given `depth`.

## Fields

  * `id` — `integer() | nil` — primary key
  * `ancestor_id` — `integer() | nil` — ancestor account id (e.g. `1`)
  * `descendant_id` — `integer() | nil` — descendant account id (e.g. `4`)
  * `depth` — `integer() | nil` — 0 for self, 1 for child, 2 for grandchild
  * `inserted_at` — `DateTime.t() | nil` — set on insert (no `updated_at`)

## Example

    %Logistiki.VirtualAccounts.VirtualAccountClosure{
      ancestor_id: 1, descendant_id: 4, depth: 3
    }
