Struct fluvio_smartmodule::RecordData

pub struct RecordData(_);

A type containing the data contents of a Record.

The RecordData type provides useful conversions for constructing it from any type that may convert into a Vec<u8>. This is the basis for flexible APIs that allow users to supply various different argument types as record contents. See the Producer API as an example.

Implementations

impl RecordData

pub fn len(&self) -> usize

pub fn is_binary(&self) -> bool

Check if value is binary content

pub fn describe(&self) -> String

Describe value - return text, binary, or 0 bytes

pub fn as_str(&self) -> Result<&str, Utf8Error>

Trait Implementations

impl AsRef<[u8]> for RecordData

fn as_ref(&self) -> &[u8]

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for RecordData

fn clone(&self) -> RecordData

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for RecordData

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

Formats the value using the given formatter.

impl Decoder for RecordData

fn decode<T>(&mut self, src: &mut T, _: i16) -> Result<(), Error>where
    T: Buf,

fn decode_from<T>(src: &mut T, version: i16) -> Result<Self, Error>where
    T: Buf,
    Self: Default,

decode Fluvio compliant protocol values from buf

impl Default for RecordData

fn default() -> RecordData

Returns the “default value” for a type.

impl Display for RecordData

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

Formats the value using the given formatter.

impl Encoder for RecordData

fn write_size(&self, version: i16) -> usize

size of this object in bytes

fn encode<T>(&self, dest: &mut T, version: i16) -> Result<(), Error>where
    T: BufMut,

encoding contents for buffer

fn as_bytes(&self, version: i16) -> Result<Bytes, Error>

impl<V> From<V> for RecordDatawhere
    V: Into<Vec<u8, Global>>,

fn from(value: V) -> RecordData

Converts to this type from the input type.

impl PartialEq<RecordData> for RecordData

fn eq(&self, other: &RecordData) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
