Struct RecordHeader

pub struct RecordHeader { /* private fields */ }

A key value pair attached to a Record.

Headers are opaque to the broker and are purely a mechanism for the producer and consumers to pass information.

Implementations

impl RecordHeader

pub fn new(key: Vec<u8>, value: Option<Vec<u8>>) -> RecordHeader

Create a new RecordHeader.

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

Returns the header’s key.

pub fn set_key(&mut self, k: Vec<u8>)

Sets the key for this header.

pub fn value(&self) -> Option<&[u8]>

Returns the header’s value or None if there is no value.

pub fn set_value(&mut self, v: Vec<u8>)

Sets the value for this header.

Trait Implementations

impl Clone for RecordHeader

fn clone(&self) -> RecordHeader

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RecordHeader

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

Formats the value using the given formatter.

impl Default for RecordHeader

fn default() -> RecordHeader

Returns the “default value” for a type.

impl<'a> From<&'a RecordHeader> for BorrowedHeader<'a>

fn from(header: &'a RecordHeader) -> BorrowedHeader<'a>

Converts to this type from the input type.

impl PartialEq for RecordHeader

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