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: customize.rs
    path of file: ./repos/aws-sdk-rust/sdk/ecr/src/client
    
    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.
/// `CustomizableOperation` allows for configuring a single operation invocation before it is sent.
pub struct 
    
    pub(crate) fn new(customizable_send: B) -> Self {
        Self {
            customizable_send,
            config_override: ::std::option::Option::None,
            interceptors: vec![],
            runtime_plugins: vec![],
            _output: ::std::marker::PhantomData,
            _error: ::std::marker::PhantomData,
        }
    }
