Struct google_api_proto::google::dataflow::v1beta3::Step

pub struct Step {
    pub kind: String,
    pub name: String,
    pub properties: Option<Struct>,
}

Defines a particular step within a Cloud Dataflow job.

A job consists of multiple steps, each of which performs some specific operation as part of the overall job. Data is typically passed from one step to another as part of the job.

Here’s an example of a sequence of steps which together implement a Map-Reduce job:

• Read a collection of data from some source, parsing the collection’s elements.

• Validate the elements.

• Apply a user-defined function to map each element to some value and extract an element-specific key value.

• Group elements with the same key into a single element with that key, transforming a multiply-keyed collection into a uniquely-keyed collection.

• Write the elements out to some data sink.

Note that the Cloud Dataflow service may be used to run many different types of jobs, not just Map-Reduce.

Fields

kind: String

The kind of step in the Cloud Dataflow job.

name: String

The name that identifies the step. This must be unique for each step with respect to all other steps in the Cloud Dataflow job.

properties: Option<Struct>

Named properties associated with the step. Each kind of predefined step has its own required set of properties. Must be provided on Create. Only retrieved with JOB_VIEW_ALL.

Trait Implementations

impl Clone for Step

fn clone(&self) -> Step

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Step

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

Formats the value using the given formatter.

impl Default for Step

fn default() -> Self

Returns the “default value” for a type.

impl Message for Step

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 Step

fn eq(&self, other: &Step) -> 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.
