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: _csv_mapping_parameters.rs
    path of file: ./repos/aws-sdk-rust/sdk/kinesisanalyticsv2/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>For a SQL-based Kinesis Data Analytics application, provides additional mapping information when the record format uses delimiters, such as CSV. For example, the following sample records use CSV format, where the records use the <i>'\n'</i> as the row delimiter and a comma (",") as the column delimiter:</p>
/// <p><code>"name1", "address1"</code></p>
/// <p><code>"name2", "address2"</code></p>
