Struct Response

pub struct Response<'a> { /* private fields */ }

Implementations

impl<'a> Response<'a>

pub fn remove_header(&mut self, key: String)

Remove a pair you have writed to a reponse header

• The key is not case senstive

For example

add_header(String::from("a"),String::from("b"))

Header: {a:b}

remove_header(String::from("a"))

Header: {}

pub fn add_header(&mut self, key: String, value: String)

Add a pair to the header of the response

add_header(String::from("a"),String::from("b"))

Header:{a:b}

pub fn header_exist(&self, s: &str) -> bool

Check whether a pair exists in the header of a reponse

For example

assume the header is {a:b}

header_exist("a") returns true

The key is not case senstive

pub fn get_header(&self, k: &str) -> Option<&Vec<String>>

Get response header

• Return a Vector since a single key can correspond to multiple values in the response header.

pub fn write_string(&mut self, v: &str) -> ResponseConfig<'_, 'a>

Write a utf-8 String to client

pub fn write_binary(&mut self, v: Vec<u8>) -> ResponseConfig<'_, 'a>

Write binary data to client

pub fn write_state(&mut self, code: u16)

Only respond HTTP status to the client

pub fn write_file(&mut self, path: String) -> ResponseConfig<'_, 'a>

Write file data to the client

pub fn render_view( &mut self, factory: impl Fn(&Request<'_>) -> Result<String>, context: &Request<'_>, ) -> ResponseConfig<'_, 'a>

Render a view to the client

• factory implements Fn() -> tera::Result

• The factory permits you customize the behavior of the tera engine

pub fn render_view_once( &mut self, path: &str, context: &Context, ) -> ResponseConfig<'_, 'a>

Only use the default configured tera to render a view to the client

• path: path of view file
• context: used in the view

pub fn get_conn(&self) -> Rc<RefCell<&'a mut TcpStream>>
