Protobuf type alias

by

A protocol buffer type alias is a way to define a new name for an existing protocol buffer type. It allows you to create a shorter or more descriptive name for a type, which can be helpful for code readability and maintainability.

To define a type alias in protocol buffers, you can use the “import” statement to import the original type definition, and then use the “type” statement to create a new alias for that type.

Here’s an example:

// original type definition
syntax = "proto3";
package example;

message Person {
  string name = 1;
  int32 age = 2;
}

// type alias definition
import "example.proto"; // import the original type
syntax = "proto3";

message AliasPerson {
  example.Person person = 1; // use the original type as the alias
}

In the example above, we have defined a type alias called “AliasPerson” for the “Person” message defined in the “example.proto” file. By using this type alias, we can refer to the original “Person” message with a shorter and more descriptive name.
