Struct MessageMeta 

pub struct MessageMeta(pub Bytes);

Extract the raw metadata of a message from a frame. This gives you the unprocessed metadata of the message in Bytes form. Other parts of the system presume JSON encoding and things like that, but this will let you determine what format you like.

Tuple Fields

0: Bytes

Trait Implementations

impl Clone for MessageMeta

fn clone(&self) -> MessageMeta

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MessageMeta

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

Formats the value using the given formatter.

impl<State> Extractor<State> for MessageMeta

type Error = MessageFrameError

The error type for this extractor. Anything that can be converted into an extractor error can be used as an error type.

fn extract(frame: Frame, context: &Context<State>) -> Result<Self, Self::Error>

where Self: Sized,

Take an frame and a state and return a result containing the extracted value or the frame.

fn extract_from_frame_and_state( frame: Frame, context: &Context<State>, ) -> Result<Self>

where Self: Sized, Self::Error: Into<ExtractorError>,

Extract a value from a frame and state, returning a result containing the extracted value or an error coerced into a crate::Error.

impl PartialEq for MessageMeta

fn eq(&self, other: &MessageMeta) -> 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.
