Struct wamp_core::messages::cancel::Cancel

pub struct Cancel {
    pub request_id: u64,
    pub options: Value,
}

Cancel - wamp-proto

Represents an Cancel message in the WAMP protocol.

Examples

use wamp_core::messages::Cancel;
use wamp_core::cancel;
use serde_json::json;

let cancel_message = Cancel {
    request_id: 1,
    options: json!({})
};

Serializer

Implements serde Serialize trait for Cancel

use wamp_core::messages::Cancel;
use serde_json::{json, to_string};

// Create an Cancel message
let cancel = Cancel {
    request_id: 1,
    options: json!({ "key": "value" })
};

// Establish raw json data string
let data = r#"[49,1,{"key":"value"}]"#;

// Here we convert it from an `Cancel` frame, to a string representation.
let cancel = to_string(&cancel).unwrap();

// Confirm that our Cancel frame strings are equal to each other
assert_eq!(cancel, data);

Deserializer

Implements serde Deserialize trait for Cancel

use wamp_core::messages::Cancel;
use serde_json::from_str;

// Here is our raw json data string
let data = r#"[49,1,{}]"#;

// Here we convert it to an `Cancel` frame
let cancel = from_str::<Cancel>(data).unwrap();

// Confirm that our request_id and options deserialized
assert_eq!(cancel.request_id, 1);
assert_eq!(cancel.options, serde_json::json!({}));

Fields

request_id: u64

options: Value

Trait Implementations

impl Clone for Cancel

fn clone(&self) -> Cancel

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Cancel

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Cancel

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<Cancel> for Messages

fn from(v: Cancel) -> Messages

Converts to this type from the input type.

impl From<Messages> for Cancel

fn from(v: Messages) -> Cancel

Converts to this type from the input type.

impl PartialEq for Cancel

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl Serialize for Cancel

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.

impl TryFrom<Cancel> for Message

type Error = Error

The type returned in the event of a conversion error.

fn try_from(value: Cancel) -> Result<Message, Self::Error>

Performs the conversion.

impl WampMessage for Cancel

const ID: u64 = 49u64

fn direction(role: Roles) -> &'static MessageDirection

Direction method
