Fields§
§column_type: Option<DataType>
§column_id: i32
§name: String
we store the column name in column desc now just for debug, but in future we should store it in ColumnCatalog but not here
description: Option<String>
This field is used to store the description set by the comment on
clause.
additional_column_type: i32
deprecated, use AdditionalColumn instead, keep for compatibility with v1.6.x
version: i32
§additional_column: Option<AdditionalColumn>
§generated_or_default_column: Option<GeneratedOrDefaultColumn>
Optional description for the generated column or default value.
Implementations§
source§impl ColumnDesc
impl ColumnDesc
sourcepub fn description(&self) -> &str
pub fn description(&self) -> &str
Returns the value of description
, or the default value if description
is unset.
sourcepub fn additional_column_type(&self) -> AdditionalColumnType
pub fn additional_column_type(&self) -> AdditionalColumnType
Returns the enum value of additional_column_type
, or the default if the field is set to an invalid enum value.
sourcepub fn set_additional_column_type(&mut self, value: AdditionalColumnType)
pub fn set_additional_column_type(&mut self, value: AdditionalColumnType)
Sets additional_column_type
to the provided enum value.
sourcepub fn version(&self) -> ColumnDescVersion
pub fn version(&self) -> ColumnDescVersion
Returns the enum value of version
, or the default if the field is set to an invalid enum value.
sourcepub fn set_version(&mut self, value: ColumnDescVersion)
pub fn set_version(&mut self, value: ColumnDescVersion)
Sets version
to the provided enum value.
