Struct mz_postgres_util::desc::PostgresTableDesc

pub struct PostgresTableDesc {
    pub oid: Oid,
    pub namespace: String,
    pub name: String,
    pub columns: Vec<PostgresColumnDesc>,
    pub keys: BTreeSet<PostgresKeyDesc>,
}

Describes a table in a PostgreSQL database.

Fields

oid: Oid

The OID of the table.

namespace: String

The name of the schema that the table belongs to.

name: String

The name of the table.

columns: Vec<PostgresColumnDesc>

The description of each column, in order of their position in the table.

keys: BTreeSet<PostgresKeyDesc>

Applicable keys for this table (i.e. primary key and unique constraints).

Implementations

impl PostgresTableDesc

pub fn determine_compatibility( &self, other: &PostgresTableDesc, allow_type_to_change_by_col_num: &BTreeSet<u16>, ) -> Result<(), Error>

Determines if two PostgresTableDesc are compatible with one another in a way that Materialize can handle.

Currently this means that the values are equal except for the following exceptions:

• self’s columns are a compatible prefix of other’s columns. Compatibility is defined as returning true for PostgresColumnDesc::is_compatible.
• self’s keys are all present in other

Trait Implementations

impl Arbitrary for PostgresTableDesc

type Parameters = (<u32 as Arbitrary>::Parameters, <String as Arbitrary>::Parameters, <String as Arbitrary>::Parameters)

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

type Strategy = Map<(<u32 as Arbitrary>::Strategy, <String as Arbitrary>::Strategy, <String as Arbitrary>::Strategy, BoxedStrategy<Vec<PostgresColumnDesc>>, BoxedStrategy<BTreeSet<PostgresKeyDesc>>), fn(_: (u32, String, String, Vec<PostgresColumnDesc>, BTreeSet<PostgresKeyDesc>)) -> PostgresTableDesc>

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 PostgresTableDesc

fn clone(&self) -> PostgresTableDesc

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PostgresTableDesc

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for PostgresTableDesc

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for PostgresTableDesc

fn eq(&self, other: &PostgresTableDesc) -> 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<ProtoPostgresTableDesc> for PostgresTableDesc

fn into_proto(&self) -> ProtoPostgresTableDesc

Convert a Self into a Proto value.

fn from_proto(proto: ProtoPostgresTableDesc) -> 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 PostgresTableDesc

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
