Struct mysql_async::binlog::events::UpdateRowsEvent

pub struct UpdateRowsEvent<'a>(/* private fields */);

Update rows event.

Used for row-based binary logging. Contains as much data as needed to identify a row + the data to change.

Implementations

impl<'a> UpdateRowsEvent<'a>

pub fn table_id(&self) -> u64

Returns the number that identifies the table (see TableMapEvent).

pub fn num_columns(&self) -> u64

Returns the number of columns in the table.

pub fn columns_before_image(&'a self) -> &'a BitSlice<u8>

Returns columns in the before-image (only for DELETE and UPDATE).

Each bit indicates whether corresponding column is used in the image.

pub fn columns_after_image(&'a self) -> &'a BitSlice<u8>

Returns columns in the after-image (only for WRITE and UPDATE).

Each bit indicates whether corresponding column is used in the image.

pub fn rows_data(&'a self) -> &'a [u8]

Returns raw rows data.

pub fn rows( &'a self, table_map_event: &'a TableMapEvent<'a> ) -> RowsEventRows<'a>

Returns an iterator over event’s rows given the corresponding TableMapEvent.

pub fn into_owned(self) -> UpdateRowsEvent<'static>

Trait Implementations

impl<'a> BinlogEvent<'a> for UpdateRowsEvent<'a>

const EVENT_TYPE: EventType = EventType::UPDATE_ROWS_EVENT

An event type, associated with this struct (if any).

impl<'a> BinlogStruct<'a> for UpdateRowsEvent<'a>

fn len(&self, version: BinlogVersion) -> usize

Returns serialized length of this struct in bytes.

impl<'a> Clone for UpdateRowsEvent<'a>

fn clone(&self) -> UpdateRowsEvent<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for UpdateRowsEvent<'a>

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

Formats the value using the given formatter.

impl<'a> Hash for UpdateRowsEvent<'a>

fn hash<__H>(&self, state: &mut __H)where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<'de> MyDeserialize<'de> for UpdateRowsEvent<'de>

const SIZE: Option<usize> = RowsEvent::SIZE

Size hint of a serialized value (in bytes), if it’s constant.

type Ctx = BinlogCtx<'de>

Some structs defines deserialization in the context of another value.

fn deserialize( ctx: <UpdateRowsEvent<'de> as MyDeserialize<'de>>::Ctx, buf: &mut ParseBuf<'de> ) -> Result<UpdateRowsEvent<'de>, Error>

Deserializes self from the given buf.

impl MySerialize for UpdateRowsEvent<'_>

fn serialize(&self, buf: &mut Vec<u8>)

Serializes self into the buf.

impl<'a> PartialEq for UpdateRowsEvent<'a>

fn eq(&self, other: &UpdateRowsEvent<'a>) -> 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.
