pub const REAL: MssqlTypeInfo

REAL type information.

pub const SMALLINT: MssqlTypeInfo

SMALLINT type information.

pub const TINYINT: MssqlTypeInfo

TINYINT type information.

pub const UNKNOWN: MssqlTypeInfo

UNKNOWN type information.

pub const TIME: MssqlTypeInfo

TIME type information with zero fractional precision.

pub const TIMESTAMP: MssqlTypeInfo

pub const fn new(data_type: DataType) -> MssqlTypeInfo

Creates type information from an odbc-api data type.

pub const fn data_type(&self) -> DataType

Returns the underlying odbc-api data type.

pub const fn char(length: Option<NonZero<usize>>) -> MssqlTypeInfo

Creates CHAR type information.

pub const fn float(precision: usize) -> MssqlTypeInfo

Creates FLOAT type information.

pub const fn time(precision: i16) -> MssqlTypeInfo

Creates TIME type information.

pub const fn timestamp(precision: i16) -> MssqlTypeInfo

Creates TIMESTAMP type information.

pub const fn varchar(length: Option<NonZero<usize>>) -> MssqlTypeInfo

Creates VARCHAR type information.

pub const fn varbinary(length: Option<NonZero<usize>>) -> MssqlTypeInfo

Creates VARBINARY type information.

pub const fn decimal(precision: usize, scale: i16) -> MssqlTypeInfo

Creates DECIMAL type information.

pub const fn numeric(precision: usize, scale: i16) -> MssqlTypeInfo

Creates NUMERIC type information.

pub const fn guid() -> MssqlTypeInfo

Creates UNIQUEIDENTIFIER (GUID) type information.

MSSQL reports this as DataType::Other with SQL type code -11 (SQL_GUID).

pub const fn xml() -> MssqlTypeInfo

Creates XML type information.

MSSQL reports this as DataType::Other with SQL type code -152 (SQL_SS_XML).

pub const fn datetimeoffset() -> MssqlTypeInfo

Creates DATETIMEOFFSET type information.

MSSQL reports this as DataType::Other with SQL type code -155 (SQL_SS_TIMESTAMPOFFSET).

pub const fn geometry() -> MssqlTypeInfo

Creates GEOMETRY/GEOGRAPHY (spatial UDT) type information.

MSSQL reports spatial types as DataType::Other with SQL type code -151 (SQL_SS_UDT — CLR User-Defined Type), which covers both geometry and geography columns.

Trait Implementations

impl Clone for MssqlTypeInfo

fn clone(&self) -> MssqlTypeInfo

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MssqlTypeInfo

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for MssqlTypeInfo

fn deserialize<D>( deserializer: D, ) -> Result<MssqlTypeInfo, <D as Deserializer<'de>>::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for MssqlTypeInfo

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

Formats the value using the given formatter.

impl Eq for MssqlTypeInfo

impl PartialEq for MssqlTypeInfo

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

impl Serialize for MssqlTypeInfo

fn serialize<S>( &self, serializer: S, ) -> Result<<S as Serializer>::Ok, <S as Serializer>::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.

impl StructuralPartialEq for MssqlTypeInfo

impl TypeInfo for MssqlTypeInfo

fn is_null(&self) -> bool

fn name(&self) -> &str

Returns the database system name of the type. Length specifiers should not be included. Common type names are VARCHAR, TEXT, or INT. Type names should be uppercase. They should be a rough approximation of how they are written in SQL in the given database.

fn type_compatible(&self, other: &Self) -> bool

where Self: Sized,

Return true if self and other represent mutually compatible types.
