Enum TypeInfo 

pub enum TypeInfo {
    FixedLen(FixedLenType),
    VarLenSized(VarLenContext),
    VarLenSizedPrecision {
        ty: VarLenType,
        size: usize,
        precision: u8,
        scale: u8,
    },
    Xml {
        schema: Option<Arc<XmlSchema>>,
        size: usize,
    },
}

Describes a type of a column.

Variants

FixedLen(FixedLenType)

A fixed-length TDS type.

VarLenSized(VarLenContext)

A variable-length TDS type with optional collation metadata.

VarLenSizedPrecision

A variable-length TDS type that also carries precision and scale.

Fields

ty: VarLenType

The variable-length TDS type tag.

size: usize

The storage size in bytes.

precision: u8

Numeric precision.

scale: u8

Numeric scale.

Xml

XML metadata.

Fields

schema: Option<Arc<XmlSchema>>

Optional XML schema metadata.

size: usize

The XML type size marker.

Trait Implementations

impl Clone for TypeInfo

fn clone(&self) -> TypeInfo

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TypeInfo

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

Formats the value using the given formatter.

impl From<&TypeInfo> for ColumnType

fn from(ti: &TypeInfo) -> Self

Converts to this type from the input type.

impl PartialEq for TypeInfo

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