FieldType

Enumerates supported Milvus field data types and provides helpers for identifying vector types.

RETURN TYPE:

Example

Demonstrates FieldType usage.

Go

import (
	"fmt"

	"github.com/milvus-io/milvus/client/v2/entity"
)

fieldType := entity.FieldTypeFloatVector
fmt.Println(fieldType.Name())
fmt.Println(fieldType.IsVectorType())

Notes

• IsVectorType() returns true for binary, float, float16, bfloat16, sparse, and int8 vector field types.
