Column is not used as an independent entity, it is retrieved as part of a Table entity.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

name: String

Column name.

data_type: String

Column data type.

charset: String

Charset override - instead of table level charset.

collation: String

Collation override - instead of table level collation.

length: i64

Column length - e.g. varchar (50).

precision: i32

Column precision - when relevant.

scale: i32

Column scale - when relevant.

fractional_seconds_precision: i32

Column fractional second precision - used for timestamp based datatypes.

array: bool

Is the column of array type.

array_length: i32

If the column is array, of which length.

nullable: bool

Is the column nullable.

auto_generated: bool

Is the column auto-generated/identity.

udt: bool

Is the column a UDT.

custom_features: Option<Struct>

Custom engine specific features.

set_values: Vec<String>

Specifies the list of values allowed in the column. Only used for set data type.

comment: String

Comment associated with the column.

ordinal_position: i32

Column order in the table.

default_value: String

Default value of the column.

Trait Implementations

impl Clone for ColumnEntity

fn clone(&self) -> ColumnEntity

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ColumnEntity

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

Formats the value using the given formatter.

impl Default for ColumnEntity

fn default() -> ColumnEntity

Returns the “default value” for a type.

impl Message for ColumnEntity

fn typename() -> &'static str

The typename of this message.

impl PartialEq for ColumnEntity

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