Struct redis::Msg

pub struct Msg { /* private fields */ }

Represents a pubsub message.

Implementations

impl Msg

This holds the data that comes from listening to a pubsub connection. It only contains actual message data.

pub fn from_value(value: &Value) -> Option<Self>

Tries to convert provided Value into Msg.

pub fn get_channel<T: FromRedisValue>(&self) -> RedisResult<T>

Returns the channel this message came on.

pub fn get_channel_name(&self) -> &str

Convenience method to get a string version of the channel. Unless your channel contains non utf-8 bytes you can always use this method. If the channel is not a valid string (which really should not happen) then the return value is "?".

pub fn get_payload<T: FromRedisValue>(&self) -> RedisResult<T>

Returns the message’s payload in a specific format.

pub fn get_payload_bytes(&self) -> &[u8]

Returns the bytes that are the message’s payload. This can be used as an alternative to the get_payload function if you are interested in the raw bytes in it.

pub fn from_pattern(&self) -> bool

Returns true if the message was constructed from a pattern subscription.

pub fn get_pattern<T: FromRedisValue>(&self) -> RedisResult<T>

If the message was constructed from a message pattern this can be used to find out which one. It’s recommended to match against an Option<String> so that you do not need to use from_pattern to figure out if a pattern was set.

Trait Implementations

impl Debug for Msg

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

Formats the value using the given formatter.
