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: _copy_source_image_set_information.rs
    path of file: ./repos/aws-sdk-rust/sdk/medicalimaging/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>Copy source image set information.</p>
#[non_exhaustive]
#[derive(::std::clone::Clone, ::std::cmp::PartialEq, ::std::fmt::Debug)]
pub struct CopySourceImageSetInformation {
    /// <p>The latest version identifier for the source image set.</p>
    pub latest_version_id: ::std::string::S
    
    pub fn build(self) -> ::std::result::Result<crate::types::CopySourceImageSetInformation, ::aws_smithy_types::error::operation::BuildError> {
        ::std::result::Result::Ok(crate::types::CopySourceImageSetInformation {
            latest_version_id: self.latest_version_id.ok_or_else(|| {

                    "latest_version_id",
                    "latest_version_id was not specified but it is required when building CopySourceImageSetInformation",
                )
