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: _reusable_delegation_set_limit.rs
    path of file: ./repos/aws-sdk-rust/sdk/route53/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 complex type that contains the type of limit that you specified in the request and the current value for that limit.</p>
#[non_exhaustive]
#[derive(::std::clone::Clone, ::std::cmp::PartialEq, ::std::fmt::Debug)]
pub struct ReusableDelegationSetLimit {
    /// <p>The limit that you requested: <code>MAX_ZONES_BY_REUSABLE_DELEGATION_SET</code>, the maximum number of hosted zones that you can associate with the specified reusable delegation set.</p>
    pub r#type: crate::typ
    
    pub fn build(self) -> ::std::result::Result<crate::types::ReusableDelegationSetLimit, ::aws_smithy_types::error::operation::BuildError> {
        ::std::result::Result::Ok(crate::types::ReusableDelegationSetLimit {
