# `Bolty.Types.Vector`

A typed vector of floating-point values, as introduced in Bolt 6.0 (Neo4j 2026.05+).

Requires a connection negotiated at Bolt 6.0 or later — packing a Vector over
an older connection raises `Bolty.Error` with code `:vector_requires_bolt_6`.

## Fields
- `type` — element precision: `:float32` (IEEE-754 single) or `:float64` (IEEE-754 double)
- `data` — list of float values

## Example

    alias Bolty.Types.Vector

    # Pass a vector as a query parameter (works on Community Edition):
    embedding = Vector.new(:float32, [0.1, 0.2, 0.3])
    [%{"v" => result}] = Bolty.query!(conn, "RETURN $v AS v", %{v: embedding})

    # Storing vectors as node properties requires Neo4j Enterprise Edition:
    Bolty.query!(conn, "CREATE (n:Item {embedding: $v})", %{v: embedding})

# `element_type`

```elixir
@type element_type() :: :float32 | :float64
```

# `t`

```elixir
@type t() :: %Bolty.Types.Vector{data: [float()], type: element_type()}
```

# `new`

```elixir
@spec new(:float32 | :float64, [float()]) :: t()
```
