Struct mysql::binlog::events::TableMapEvent

pub struct TableMapEvent<'a> { /* fields omitted */ }

Table map event.

In row-based mode, every row operation event is preceded by a Table_map_event which maps a table definition to a number.

Implementations

impl<'a> TableMapEvent<'a>

pub fn table_id(&self) -> u64

Returns the table identifier.

pub fn columns_count(&self) -> u64

Returns the number of columns

pub fn json_column_count(&self) -> usize

Ruturns a number of JSON columns.

pub fn null_bitmask(&'a self) -> &'a BitSlice<Lsb0, u8>

Returns null-bitmap for this table.

For each column this null bitmap contains a bit indicating whether data in the column can be NULL or not.

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

Returns raw database name value.

pub fn database_name(&'a self) -> Cow<'a, str>

Returns database name as a string (lossy converted).

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

Returns raw table name value.

pub fn table_name(&'a self) -> Cow<'a, str>

Returns table name as a string (lossy converted).

pub fn get_column_type(
    &self,
    col_idx: usize
) -> Result<Option<ColumnType>, UnknownColumnType>

Returns a type of the given column.

None means that the column index is out of range.

pub fn get_column_metadata(&self, col_idx: usize) -> Option<&[u8]>

Returns metadata for the given column.

Returns None if column index is out of bounds or if offset couldn’t be calculated (e.g. because of unknown column type between 0 and col_idx).

pub fn iter_optional_meta(&'a self) -> OptionalMetadataIter<'a>

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

Returns a 'static version of self.

impl<'de> MyDeserialize<'de> for TableMapEvent<'de>

pub const SIZE: Option<usize>

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.

pub fn deserialize(
    ctx: <TableMapEvent<'de> as MyDeserialize<'de>>::Ctx,
