Struct Message 

pub struct Message {
    pub offset: u64,
    pub timestamp: u64,
    pub key: Option<Vec<u8>>,
    pub value: Vec<u8>,
    pub headers: Vec<(String, Vec<u8>)>,
}

A message stored in a partition.

Fields

offset: u64

Monotonic offset within the partition.

timestamp: u64

Unix timestamp in seconds when the message was produced.

key: Option<Vec<u8>>

Optional key for keyed partitioning.

value: Vec<u8>

Message payload.

headers: Vec<(String, Vec<u8>)>

User-defined headers.

Implementations

impl Message

pub fn new(offset: u64, timestamp: u64, value: Vec<u8>) -> Self

Create a new message with the given offset, timestamp, and value.

pub fn keyed(offset: u64, timestamp: u64, key: Vec<u8>, value: Vec<u8>) -> Self

Create a keyed message.

pub fn with_header(self, name: &str, value: Vec<u8>) -> Self

Add a header to the message.

Trait Implementations

impl Clone for Message

fn clone(&self) -> Message

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Message

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Message

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Message

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

impl Serialize for Message

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
