Struct SqlServerTableDesc

pub struct SqlServerTableDesc {
    pub schema_name: Arc<str>,
    pub name: Arc<str>,
    pub columns: Box<[SqlServerColumnDesc]>,
}

Materialize compatible description of a table in Microsoft SQL Server.

See SqlServerTableRaw for the raw information we read from the upstream system.

Note: We map a SqlServerTableDesc to a Materialize RelationDesc as part of purification. Specifically we use this description to generate a SQL statement for subsource and it’s the parsing of that statement which actually generates a RelationDesc.

Fields

schema_name: Arc<str>

Name of the schema that the table belongs to.

name: Arc<str>

Name of the table.

columns: Box<[SqlServerColumnDesc]>

Columns for the table.

Implementations

impl SqlServerTableDesc

pub fn new(raw: SqlServerTableRaw) -> Self

Creating a SqlServerTableDesc from a SqlServerTableRaw description.

Note: Not all columns from SQL Server can be ingested into Materialize. To determine if a column is supported see SqlServerColumnDesc::is_supported.

pub fn qualified_name(&self) -> SqlServerQualifiedTableName

Returns the SqlServerQualifiedTableName for this SqlServerTableDesc.

pub fn apply_text_columns(&mut self, text_columns: &BTreeSet<&str>)

Update this SqlServerTableDesc to represent the specified columns as text in Materialize.

pub fn apply_excl_columns(&mut self, excl_columns: &BTreeSet<&str>)

Update this SqlServerTableDesc to exclude the specified columns from being replicated into Materialize.

pub fn decoder( &self, desc: &RelationDesc, ) -> Result<SqlServerRowDecoder, SqlServerError>

Returns a SqlServerRowDecoder which can be used to decode tiberius::Rows into mz_repr::Rows that match the shape of the provided RelationDesc.

Trait Implementations

impl Arbitrary for SqlServerTableDesc

type Parameters = (<Arc<str> as Arbitrary>::Parameters, <Arc<str> as Arbitrary>::Parameters, <Box<[SqlServerColumnDesc]> 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, <Arc<str> as Arbitrary>::Strategy, <Box<[SqlServerColumnDesc]> as Arbitrary>::Strategy), fn((Arc<str>, Arc<str>, Box<[SqlServerColumnDesc]>)) -> SqlServerTableDesc>

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 SqlServerTableDesc

fn clone(&self) -> SqlServerTableDesc

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SqlServerTableDesc

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for SqlServerTableDesc

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for SqlServerTableDesc

fn eq(&self, other: &SqlServerTableDesc) -> 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<ProtoSqlServerTableDesc> for SqlServerTableDesc

fn into_proto(&self) -> ProtoSqlServerTableDesc

Convert a Self into a Proto value.

fn from_proto(proto: ProtoSqlServerTableDesc) -> 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 SqlServerTableDesc

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
