You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: _can_interface.rs
    path of file: ./repos/aws-sdk-rust/sdk/iotfleetwise/src/types
    
    the code of the file until where you have to start completion: // Code generated by software.amazon.smithy.rust.codegen.smithy-rs. DO NOT EDIT.

/// <p>A single controller area network (CAN) device interface.</p>
#[non_exhaustive]
#[derive(::std::clone::Clone, ::std::cmp::PartialEq, ::std::fmt::Debug)]

    /// <p>The unique name of the interface.</p>
    pub name: ::std::string::String,
    /// <p>The name of the communication protocol for the interface.</p>
    pub pr
    
    pub fn build(self) -> ::std::result::Result<crate::types::CanInterface, ::aws_smithy_types::error::operation::BuildError> {
        ::std::result::Result::Ok(crate::types::CanInterface {

                    "name was not specified but it is required when building CanInterface",
                )
