Methods

impl<'a> StreamMessage<'a>

fn from_str(json: &'a str) -> Result<Self>

Parse a JSON string returned from Twitter Streaming API.

Note that this method is not a member of the FromStr trait. It is because the method requires the lifetime information of the JSON string, while FromStr::from_str does not take a lifetime parameter.

use twitter_stream_message::message::{Delete, StreamMessage};

let parsed = StreamMessage::from_str(r#"{
    "delete":{
        "status":{
            "id":1234,
            "id_str":"1234",
            "user_id":3,
            "user_id_str":"3"
        }
    }
}"#).unwrap();
let expected = StreamMessage::Delete(Delete {
    id: 1234,
    user_id: 3,
});

assert_eq!(parsed, expected);

Trait Implementations

impl<'a> Clone for StreamMessage<'a>

fn clone(&self) -> StreamMessage<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for StreamMessage<'a>

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl<'a> PartialEq for StreamMessage<'a>

fn eq(&self, __arg_0: &StreamMessage<'a>) -> bool

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

fn ne(&self, __arg_0: &StreamMessage<'a>) -> bool

This method tests for !=.

impl<'de: 'a, 'a> Deserialize<'de> for StreamMessage<'a>

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error> where
    D: Deserializer<'de>, 

Deserialize this value from the given Serde deserializer.
