Struct mysql_async::binlog::events::Event

pub struct Event { /* private fields */ }

Raw binlog event.

A binlog event starts with a Binlog Event header and is followed by a Binlog Event Type specific data part.

Implementations

impl Event

pub fn read<'a, T>( fde: &'a FormatDescriptionEvent<'a>, input: T, ) -> Result<Event, Error>

where T: Read,

Reads an event from input.

pub fn write<T>(&self, version: BinlogVersion, output: T) -> Result<(), Error>

where T: Write,

Writes this event into the output.

pub fn fde(&self) -> &FormatDescriptionEvent<'static>

Returns a reference to the corresponding format description event.

pub fn header(&self) -> BinlogEventHeader

Returns a reference to the event header.

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

Returns a reference to the event data.

pub fn footer(&self) -> BinlogEventFooter

Returns a reference to the event footer.

pub fn checksum(&self) -> Option<[u8; 4]>

Returns the checksum, if it is defined.

pub fn read_event<'a, T>(&'a self) -> Result<T, Error>

where T: BinlogEvent<'a>,

Read event-type specific data as a binlog struct.

pub fn read_data(&self) -> Result<Option<EventData<'_>>, Error>

Reads event data. Returns None if event type is unknown.

pub fn calc_checksum(&self, alg: BinlogChecksumAlg) -> u32

Calculates checksum for this event.

Trait Implementations

impl Clone for Event

fn clone(&self) -> Event

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Event

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

Formats the value using the given formatter.

impl PartialEq for Event

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