Struct google_api_proto::google::cloud::clouddms::v1::ConstraintEntity

pub struct ConstraintEntity {
    pub name: String,
    pub type: String,
    pub table_columns: Vec<String>,
    pub custom_features: Option<Struct>,
    pub reference_columns: Vec<String>,
    pub reference_table: String,
    pub table_name: String,
}

Constraint is not used as an independent entity, it is retrieved as part of another entity such as Table or View.

Fields

name: String

The name of the table constraint.

type: String

Type of constraint, for example unique, primary key, foreign key (currently only primary key is supported).

table_columns: Vec<String>

Table columns used as part of the Constraint, for example primary key constraint should list the columns which constitutes the key.

custom_features: Option<Struct>

Custom engine specific features.

reference_columns: Vec<String>

Reference columns which may be associated with the constraint. For example, if the constraint is a FOREIGN_KEY, this represents the list of full names of referenced columns by the foreign key.

reference_table: String

Reference table which may be associated with the constraint. For example, if the constraint is a FOREIGN_KEY, this represents the list of full name of the referenced table by the foreign key.

table_name: String

Table which is associated with the constraint. In case the constraint is defined on a table, this field is left empty as this information is stored in parent_name. However, if constraint is defined on a view, this field stores the table name on which the view is defined.

Trait Implementations

impl Clone for ConstraintEntity

fn clone(&self) -> ConstraintEntity

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ConstraintEntity

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

Formats the value using the given formatter.

impl Default for ConstraintEntity

fn default() -> Self

Returns the “default value” for a type.

impl Message for ConstraintEntity

fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

fn clear(&mut self)

Clears the message, resetting all fields to their default.

fn encode(&self, buf: &mut impl BufMut) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message to a buffer.

fn encode_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message to a newly allocated buffer.

fn encode_length_delimited( &self, buf: &mut impl BufMut, ) -> Result<(), EncodeError>

where Self: Sized,

Encodes the message with a length-delimiter to a buffer.

fn encode_length_delimited_to_vec(&self) -> Vec<u8>

where Self: Sized,

Encodes the message with a length-delimiter to a newly allocated buffer.

fn decode(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes an instance of the message from a buffer.

fn decode_length_delimited(buf: impl Buf) -> Result<Self, DecodeError>

where Self: Default,

Decodes a length-delimited instance of the message from the buffer.

fn merge(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes an instance of the message from a buffer, and merges it into self.

fn merge_length_delimited(&mut self, buf: impl Buf) -> Result<(), DecodeError>

where Self: Sized,

Decodes a length-delimited instance of the message from buffer, and merges it into self.

impl PartialEq for ConstraintEntity

fn eq(&self, other: &ConstraintEntity) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
