Proto Repeated Custom Item Syntax

I came across this code:

message MapTaskAssignment {
  uint32 task = 1;
  uint32 worker_id = 2;
}

message GetTaskReply {
  ...
  repeated MapTaskAssignment map_task_assignments = 10;
}

I've seen repeated string before. But what does it mean when the repeated item is another proto object (repeated MapT开发者_StackOverflowaskAssignment)? How does it work and how can I access the fields inside?

Edit: Specifically, using rust, what type does repeated MapTaskAssignment convert to? is it a Vec of struct MapTaskAssignment?

In the same manner RepeatedField is defined in google/protobuf/repeated_field.h, prost - Protocol Buffers implementation for Rust defines repeated: Vec<T>.

For your sample Protocol Buffers definition tonic-build would create

pub struct MapTaskAssignment {
    #[prost(uint32, tag = "1")]
    pub task: u32,
    #[prost(uint32, tag = "2")]
    pub worker_id: u32,
}

pub struct GetTaskReply {
    #[prost(message, repeated, tag = "10")]
    pub map_task_assignments: ::prost::alloc::vec::Vec<MapTaskAssignment>,
}
