Struct mysql_common::binlog::events::TableMapEvent
source · pub struct TableMapEvent<'a> { /* private fields */ }
Expand description
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§
source§impl<'a> TableMapEvent<'a>
impl<'a> TableMapEvent<'a>
sourcepub fn columns_count(&self) -> u64
pub fn columns_count(&self) -> u64
Returns the number of columns
sourcepub fn json_column_count(&self) -> usize
pub fn json_column_count(&self) -> usize
Ruturns a number of JSON columns.
sourcepub fn null_bitmask(&'a self) -> &'a BitSlice<u8> ⓘ
pub fn null_bitmask(&'a self) -> &'a BitSlice<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.
sourcepub fn database_name_raw(&'a self) -> &'a [u8] ⓘ
pub fn database_name_raw(&'a self) -> &'a [u8] ⓘ
Returns raw database name value.
sourcepub fn database_name(&'a self) -> Cow<'a, str>
pub fn database_name(&'a self) -> Cow<'a, str>
Returns database name as a string (lossy converted).
sourcepub fn table_name_raw(&'a self) -> &'a [u8] ⓘ
pub fn table_name_raw(&'a self) -> &'a [u8] ⓘ
Returns raw table name value.
sourcepub fn table_name(&'a self) -> Cow<'a, str>
pub fn table_name(&'a self) -> Cow<'a, str>
Returns table name as a string (lossy converted).
sourcepub fn get_raw_column_type(
&self,
col_idx: usize,
) -> Result<Option<ColumnType>, UnknownColumnType>
pub fn get_raw_column_type( &self, col_idx: usize, ) -> Result<Option<ColumnType>, UnknownColumnType>
Returns raw type of the column as stored in the column_type field of the Table Map Event.
None
means that the column index is out of range.
sourcepub fn get_column_type(
&self,
col_idx: usize,
) -> Result<Option<ColumnType>, BadColumnType>
pub fn get_column_type( &self, col_idx: usize, ) -> Result<Option<ColumnType>, BadColumnType>
Returns a type of the given column.
It’ll read real column type out of the column
metadata if column type is MYSQL_TYPE_STRING
.
Returns an error in case of unknown column type
or unexpected real type for MYSQL_TYPE_STRING
.
None
means that the column index is out of range.
sourcepub fn get_column_metadata(&self, col_idx: usize) -> Option<&[u8]>
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> ⓘ
sourcepub fn into_owned(self) -> TableMapEvent<'static>
pub fn into_owned(self) -> TableMapEvent<'static>
Returns a 'static
version of self
.
