}

A setting a column can hold.

Variants

Nullable

The column can be null.

CaseSensitive

Set for string columns with binary collation and always for the XML data type.

Updateable

If column is writeable.

UpdateableUnknown

Column modification status unknown.

Identity

Column is an identity.

Computed

Coulumn is computed.

FixedLenClrType

Column is a fixed-length common language runtime user-defined type (CLR UDT).

SparseColumnSet

Column is the special XML column for the sparse column set.

Encrypted

Column is encrypted transparently and has to be decrypted to view the plaintext value. This flag is valid when the column encryption feature is negotiated between client and server and is turned on.

Hidden

Column is part of a hidden primary key created to support a T-SQL SELECT statement containing FOR BROWSE.

Key

Column is part of a primary key for the row and the T-SQL SELECT statement contains FOR BROWSE.

NullableUnknown

It is unknown whether the column might be nullable.

Trait Implementations

impl BitAnd<ColumnFlag> for ColumnFlag

type Output = BitFlags<ColumnFlag, <ColumnFlag as RawBitFlags>::Numeric>

The resulting type after applying the & operator.

fn bitand(self, other: Self) -> Self::Output

Performs the & operation.

impl BitFlag for ColumnFlag

fn empty() -> BitFlags<Self, Self::Numeric>

Create a BitFlags with no flags set (in other words, with a value of 0).

fn all() -> BitFlags<Self, Self::Numeric>

Create a BitFlags with all flags set.

impl BitOr<ColumnFlag> for ColumnFlag

type Output = BitFlags<ColumnFlag, <ColumnFlag as RawBitFlags>::Numeric>

The resulting type after applying the | operator.

fn bitor(self, other: Self) -> Self::Output

Performs the | operation.

impl BitXor<ColumnFlag> for ColumnFlag

type Output = BitFlags<ColumnFlag, <ColumnFlag as RawBitFlags>::Numeric>

The resulting type after applying the ^ operator.

fn bitxor(self, other: Self) -> Self::Output

Performs the ^ operation.

impl Clone for ColumnFlag

fn clone(&self) -> ColumnFlag

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ColumnFlag

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

Formats the value using the given formatter.

impl Not for ColumnFlag

type Output = BitFlags<ColumnFlag, <ColumnFlag as RawBitFlags>::Numeric>

The resulting type after applying the ! operator.

fn not(self) -> Self::Output

Performs the unary ! operation.

impl PartialEq<ColumnFlag> for ColumnFlag

fn eq(&self, other: &ColumnFlag) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=.

impl RawBitFlags for ColumnFlag

type Numeric = u16

The underlying integer type.

const EMPTY: Self::Numeric = {transmute(0x0000): <tds::codec::token::token_col_metadata::ColumnFlag as enumflags2::_internal::RawBitFlags>::Numeric}

A value with no bits set.

const DEFAULT: Self::Numeric = {transmute(0x0000): <tds::codec::token::token_col_metadata::ColumnFlag as enumflags2::_internal::RawBitFlags>::Numeric}

The value used by the Default implementation. Equivalent to EMPTY, unless customized.

const ALL_BITS: Self::Numeric = {transmute(0xfcbb): <tds::codec::token::token_col_metadata::ColumnFlag as enumflags2::_internal::RawBitFlags>::Numeric}

A value with all flag bits set.

const BITFLAGS_TYPE_NAME: &'static str = _

The name of the type for debug formatting purposes.

fn bits(self) -> Self::Numeric

Return the bits as a number type.
