# The MongoDB\BSON\VectorType enum

(mongodb >=2.2.0)

## Introduction

The MongoDB\BSON\VectorType enum is used to specify the type of vector data stored in a MongoDB\BSON\Binary with subtype `MongoDB\BSON\Binary::TYPE_VECTOR`.

## Enum synopsis

enum MongoDB\BSON\VectorType
{
case Float32 ; // Each element in the vector is a 32-bit floating point value.
case Int8 ; // Each element in the vector is an 8-bit integer value.
case PackedBit ; // Each element in the vector is a 1-bit value. When creating vectors of this type, you may pass either bool or 1-bit int values, i.e. `0` or `1`.
