Struct Header 

pub struct Header {
    pub key: String,
    pub value: Option<Bytes>,
}

A single Kafka record header: a string key and an opaque optional value.

Mirrors crabka_protocol::records::RecordHeader and the producer’s Header; kept here so the connector SPI does not pull in the wire-record crates.

Fields

key: String

The header key. Not required to be unique within a record.

value: Option<Bytes>

The header value, or None for a null-valued header.

Trait Implementations

impl Clone for Header

fn clone(&self) -> Header

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Header

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

Formats the value using the given formatter.

impl Default for Header

fn default() -> Header

Returns the “default value” for a type.

impl Eq for Header

impl PartialEq for Header

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