Struct SqlServerColumnDesc

pub struct SqlServerColumnDesc {
    pub name: Arc<str>,
    pub column_type: Option<ColumnType>,
    pub primary_key_constraint: Option<Arc<str>>,
    pub decode_type: SqlServerColumnDecodeType,
    pub raw_type: Arc<str>,
}

Description of a column from a table in Microsoft SQL Server.

Fields

name: Arc<str>

Name of the column.

column_type: Option<ColumnType>

The intended data type of the this column in Materialize. None indicates this column should be excluded when replicating into Materialize.

Note: This type might differ from the decode_type, e.g. a user can specify TEXT COLUMNS to decode columns as text.

primary_key_constraint: Option<Arc<str>>

If this column is part of the primary key for the table, and the name of the constraint.

decode_type: SqlServerColumnDecodeType

Rust type we should parse the data from a tiberius::Row as.

raw_type: Arc<str>

Raw type of the column as we read it from upstream.

This is useful to keep around for debugging purposes.

Implementations

impl SqlServerColumnDesc

pub fn new(raw: &SqlServerColumnRaw) -> Self

Create a SqlServerColumnDesc from a SqlServerColumnRaw description.

pub fn is_supported(&self) -> bool

Returns true if this column can be replicated into Materialize.

pub fn represent_as_text(&mut self)

Change this SqlServerColumnDesc to be represented as text in Materialize.

pub fn exclude(&mut self)

Exclude this SqlServerColumnDesc from being replicated into Materialize.

pub fn is_excluded(&self) -> bool

Check if this SqlServerColumnDesc is excluded from being replicated into Materialize.

Trait Implementations

impl Arbitrary for SqlServerColumnDesc

type Parameters = (<Arc<str> as Arbitrary>::Parameters, <Option<ColumnType> as Arbitrary>::Parameters, <Option<Arc<str>> as Arbitrary>::Parameters, <SqlServerColumnDecodeType as Arbitrary>::Parameters, <Arc<str> as Arbitrary>::Parameters)

The type of parameters that arbitrary_with accepts for configuration of the generated Strategy. Parameters must implement Default.

type Strategy = Map<(<Arc<str> as Arbitrary>::Strategy, <Option<ColumnType> as Arbitrary>::Strategy, <Option<Arc<str>> as Arbitrary>::Strategy, <SqlServerColumnDecodeType as Arbitrary>::Strategy, <Arc<str> as Arbitrary>::Strategy), fn((Arc<str>, Option<ColumnType>, Option<Arc<str>>, SqlServerColumnDecodeType, Arc<str>)) -> SqlServerColumnDesc>

The type of Strategy used to generate values of type Self.

fn arbitrary_with(_top: Self::Parameters) -> Self::Strategy

Generates a Strategy for producing arbitrary values of type the implementing type (Self). The strategy is passed the arguments given in args.

fn arbitrary() -> Self::Strategy

Generates a Strategy for producing arbitrary values of type the implementing type (Self).

impl Clone for SqlServerColumnDesc

fn clone(&self) -> SqlServerColumnDesc

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SqlServerColumnDesc

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for SqlServerColumnDesc

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for SqlServerColumnDesc

fn eq(&self, other: &SqlServerColumnDesc) -> 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 RustType<ProtoSqlServerColumnDesc> for SqlServerColumnDesc

fn into_proto(&self) -> ProtoSqlServerColumnDesc

Convert a Self into a Proto value.

fn from_proto( proto: ProtoSqlServerColumnDesc, ) -> Result<Self, TryFromProtoError>

Consume and convert a Proto back into a Self value.

fn into_proto_owned(self) -> Proto

A zero clone version of Self::into_proto that types can optionally implement, otherwise, the default implementation delegates to Self::into_proto.

impl Serialize for SqlServerColumnDesc

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
