is_hidden: bool

Implementations

impl ColumnCatalog

pub fn visible(column_desc: ColumnDesc) -> Self

pub fn hidden(column_desc: ColumnDesc) -> Self

pub fn is_hidden(&self) -> bool

Get the column catalog’s is hidden.

pub fn is_generated(&self) -> bool

If the column is a generated column

pub fn can_dml(&self) -> bool

pub fn is_user_defined(&self) -> bool

Returns whether the column is defined by user within the column definition clause in the CREATE TABLE statement.

pub fn generated_expr(&self) -> Option<&ExprNode>

If the column is a generated column

pub fn is_connector_additional_column(&self) -> bool

If the columns is an INCLUDE ... AS ... connector column.

pub fn data_type(&self) -> &DataType

Get a reference to the column desc’s data type.

pub fn nullable(&self) -> bool

Get nullable info of the column.

pub fn column_id(&self) -> ColumnId

Get the column desc’s column id.

pub fn name(&self) -> &str

Get a reference to the column desc’s name.

pub fn to_protobuf(&self) -> PbColumnCatalog

Convert column catalog to proto

pub fn row_id_column() -> Self

Creates a row ID column (for implicit primary key). It’ll always have the ID 0.

pub fn is_rw_sys_column(&self) -> bool

pub fn rw_timestamp_column() -> Self

pub fn is_rw_timestamp_column(&self) -> bool

pub fn iceberg_hidden_cols() -> [Self; 3]

pub fn debezium_cdc_source_cols() -> [Self; 3]

Note: these columns are added in SourceStreamChunkRowWriter::do_action. May also look for the usage of SourceColumnType.

pub fn is_row_id_column(&self) -> bool

impl ColumnCatalog

pub fn name_with_hidden(&self) -> Cow<'_, str>

impl PartialEq for ColumnCatalog

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