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: delete.rs
    path of file: ./repos/nushell/crates/nu-command/src/network/http
    
    the code of the file until where you have to start completion: use nu_engine::CallExt;
use nu_protocol::ast::Call;
use nu_protocol::engine::
    
    fn examples(&self) -> Vec<Example> {
        vec![
            Example {
                description: "http delete from example.com",
                example: "http delete https://www.example.com",
                result: None,
            },
            Example {
                description: "http delete from example.com, with username and password",
                example: "http delete --user myuser --password mypass https://www.example.com",
                result: None,
            },
            Example {
                description: "http delete from example.com, with custom header",
                example: "http delete --headers [my-header-key my-header-value] https://www.example.com",
                result: None,
            },
            Example {
                description: "http delete from example.com, with body",
                example: "http delete --data 'body' https://www.example.com",
                result: None,
            },
            Example {
                description: "http delete from example.com, with JSON body",
                example:
                    "http delete --content-type application/json --data { field: value } https://www.example.com",
                result: None,
            },
        ]
