FieldPartialUpdateOp

This struct describes how a field value is applied during an upsert. ArrayAppend and ArrayRemove apply only to array fields and implicitly enable partial-update semantics for the request. These array operations require Milvus 2.6.17 or later.

pub struct FieldPartialUpdateOp

PARAMETERS:

• field_name: String

  Name of the field to update.

• op_type: FieldPartialUpdateOpType

  Operation applied to the field, Replace, ArrayAppend, or ArrayRemove. Defaults to Replace.

METHODS:

• new() - Creates a value initialized with its SDK defaults.
• field_name(value) / set_field_name(value) / get_field_name() - Sets or returns the field name.
• op_type(value) / set_op_type(value) / get_op_type() - Sets or returns the operation type.

FieldPartialUpdateOpType

pub enum FieldPartialUpdateOpType {
    Replace,
    ArrayAppend,
    ArrayRemove,
}

• Replace - Overwrite the existing field value. This is the default.
• ArrayAppend - Append the supplied elements to an existing array field.
• ArrayRemove - Remove every occurrence of the supplied elements from an existing array field.

Example

let op = FieldPartialUpdateOp::new()
    .field_name("tags")
    .op_type(FieldPartialUpdateOpType::ArrayAppend);
