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

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 duplicate 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 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 Name for DdlRel

const NAME: &'static str = "DdlRel"

Simple name for this Message. This name is the same as it appears in the source .proto file, e.g. FooBar.

const PACKAGE: &'static str = "substrait"

Package name this message type is contained in. They are domain-like and delimited by ., e.g. google.protobuf.

fn full_name() -> String

Fully-qualified unique name for this Message. It’s prefixed with the package name and names of any parent messages, e.g. google.rpc.BadRequest.FieldViolation. By default, this is the package name followed by the message name. Fully-qualified names must be unique within a domain of Type URLs.

fn type_url() -> String

Type URL for this Message, which by default is the full name with a leading slash, but may also include a leading domain name, e.g. type.googleapis.com/google.profile.Person. This can be used when serializing into the google.protobuf.Any type.

impl PartialEq for DdlRel

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

Equality operator ==.

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

Inequality operator !=.
