Struct mysql_async::binlog::events::RowsEvent

pub struct RowsEvent<'a> { /* private fields */ }

Common base structure for all row-containing binary log events.

Implementations

impl<'a> RowsEvent<'a>

pub fn event_type(&self) -> EventType

Returns an actual event type of this rows event.

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) -> Option<&'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) -> Option<&'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 flags(&self) -> RowsEventFlags

Returns event flags (unknown bits are truncated).

pub fn flags_raw(&self) -> u16

Returns raw event flags (unknown bits are preserved).

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

Returns length of this event in bytes.

This function will be used in BinlogStruct implementations for derived events.

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

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

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

Trait Implementations

impl<'a> Clone for RowsEvent<'a>

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for RowsEvent<'a>

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

Formats the value using the given formatter.

impl<'a> Hash for RowsEvent<'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 RowsEvent<'de>

const SIZE: Option<usize> = None

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

type Ctx = RowsEventCtx<'de>

Some structs defines deserialization in the context of another value.

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

Deserializes self from the given buf.

impl MySerialize for RowsEvent<'_>

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

Serializes self into the buf.

impl<'a> PartialEq for RowsEvent<'a>

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