Struct Response 

#[non_exhaustive]
pub struct Response {
    pub code: i64,
    pub size: i64,
    pub headers: HashMap<String, String>,
    pub time: Option<Timestamp>,
    pub backend_latency: Option<Duration>,
    /* private fields */
}

This message defines attributes for a typical network response. It generally models semantics of an HTTP response.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

code: i64

The HTTP response status code, such as 200 and 404.

size: i64

The HTTP response size in bytes. If unknown, it must be -1.

headers: HashMap<String, String>

The HTTP response headers. If multiple headers share the same key, they must be merged according to HTTP spec. All header keys must be lowercased, because HTTP header keys are case-insensitive.

time: Option<Timestamp>

The timestamp when the destination service sends the last byte of the response.

backend_latency: Option<Duration>

The amount of time it takes the backend service to fully respond to a request. Measured from when the destination service starts to send the request to the backend until when the destination service receives the complete response from the backend.

Implementations

impl Response

pub fn new() -> Self

pub fn set_code<T: Into<i64>>(self, v: T) -> Self

Sets the value of code.

pub fn set_size<T: Into<i64>>(self, v: T) -> Self

Sets the value of size.

pub fn set_headers<T, K, V>(self, v: T) -> Self

where T: IntoIterator<Item = (K, V)>, K: Into<String>, V: Into<String>,

Sets the value of headers.

pub fn set_time<T>(self, v: T) -> Self

where T: Into<Timestamp>,

Sets the value of time.

pub fn set_or_clear_time<T>(self, v: Option<T>) -> Self

where T: Into<Timestamp>,

Sets or clears the value of time.

pub fn set_backend_latency<T>(self, v: T) -> Self

where T: Into<Duration>,

Sets the value of backend_latency.

pub fn set_or_clear_backend_latency<T>(self, v: Option<T>) -> Self

where T: Into<Duration>,

Sets or clears the value of backend_latency.

Trait Implementations

impl Clone for Response

fn clone(&self) -> Response

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Response

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Response

fn default() -> Response

Returns the “default value” for a type.

impl Message for Response

fn typename() -> &'static str

The typename of this message.

impl PartialEq for Response

fn eq(&self, other: &Response) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
