Struct DdlRel

pub struct DdlRel {
    pub table_schema: Option<NamedStruct>,
    pub table_defaults: Option<Struct>,
    pub object: i32,
    pub op: i32,
    pub view_definition: Option<Box<Rel>>,
    pub common: Option<RelCommon>,
    pub advanced_extension: Option<AdvancedExtension>,
    pub write_type: Option<WriteType>,
}

Fields

table_schema: Option<NamedStruct>

The columns that will be modified (representing after-image of a schema change)

table_defaults: Option<Struct>

The default values for the columns (representing after-image of a schema change) E.g., in case of an ALTER TABLE that changes some of the column default values, we expect the table_defaults Struct to report a full list of default values reflecting the result of applying the ALTER TABLE operator successfully

object: i32

Which type of object we operate on

op: i32

The type of operation to perform

view_definition: Option<Box<Rel>>

The body of the CREATE VIEW

common: Option<RelCommon>

advanced_extension: Option<AdvancedExtension>

write_type: Option<WriteType>

Definition of which type of object we are operating on

Implementations

impl DdlRel

pub fn object(&self) -> DdlObject

Returns the enum value of object, or the default if the field is set to an invalid enum value.

pub fn set_object(&mut self, value: DdlObject)

Sets object to the provided enum value.

pub fn op(&self) -> DdlOp

Returns the enum value of op, or the default if the field is set to an invalid enum value.

pub fn set_op(&mut self, value: DdlOp)

Sets op to the provided enum value.

Trait Implementations

impl Clone for DdlRel

fn clone(&self) -> DdlRel

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DdlRel

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

Formats the value using the given formatter.

impl Default for DdlRel

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for DdlRel

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Message for DdlRel

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 DdlRel

fn eq(&self, other: &DdlRel) -> 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 Serialize for DdlRel

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.
