Struct google_api_proto::google::cloud::dataproc::v1::TemplateParameter

pub struct TemplateParameter {
    pub name: String,
    pub fields: Vec<String>,
    pub description: String,
    pub validation: Option<ParameterValidation>,
}

A configurable parameter that replaces one or more fields in the template. Parameterizable fields:

• Labels
• File uris
• Job properties
• Job arguments
• Script variables
• Main class (in HadoopJob and SparkJob)
• Zone (in ClusterSelector)

Fields

name: String

Required. Parameter name. The parameter name is used as the key, and paired with the parameter value, which are passed to the template when the template is instantiated. The name must contain only capital letters (A-Z), numbers (0-9), and underscores (_), and must not start with a number. The maximum length is 40 characters.

fields: Vec<String>

Required. Paths to all fields that the parameter replaces. A field is allowed to appear in at most one parameter’s list of field paths.

A field path is similar in syntax to a [google.protobuf.FieldMask][google.protobuf.FieldMask]. For example, a field path that references the zone field of a workflow template’s cluster selector would be specified as placement.clusterSelector.zone.

Also, field paths can reference fields using the following syntax:

• Values in maps can be referenced by key:

  • labels[‘key’]
  • placement.clusterSelector.clusterLabels[‘key’]
  • placement.managedCluster.labels[‘key’]
  • placement.clusterSelector.clusterLabels[‘key’]
  • jobs[‘step-id’].labels[‘key’]

• Jobs in the jobs list can be referenced by step-id:

  • jobs[‘step-id’].hadoopJob.mainJarFileUri
  • jobs[‘step-id’].hiveJob.queryFileUri
  • jobs[‘step-id’].pySparkJob.mainPythonFileUri
  • jobs[‘step-id’].hadoopJob.jarFileUris[0]
  • jobs[‘step-id’].hadoopJob.archiveUris[0]
  • jobs[‘step-id’].hadoopJob.fileUris[0]
  • jobs[‘step-id’].pySparkJob.pythonFileUris[0]

• Items in repeated fields can be referenced by a zero-based index:

  • jobs[‘step-id’].sparkJob.args[0]

• Other examples:

  • jobs[‘step-id’].hadoopJob.properties[‘key’]
  • jobs[‘step-id’].hadoopJob.args[0]
  • jobs[‘step-id’].hiveJob.scriptVariables[‘key’]
  • jobs[‘step-id’].hadoopJob.mainJarFileUri
  • placement.clusterSelector.zone

It may not be possible to parameterize maps and repeated fields in their entirety since only individual map values and individual items in repeated fields can be referenced. For example, the following field paths are invalid:

• placement.clusterSelector.clusterLabels
• jobs[‘step-id’].sparkJob.args

description: String

Optional. Brief description of the parameter. Must not exceed 1024 characters.

validation: Option<ParameterValidation>

Optional. Validation rules to be applied to this parameter’s value.

Trait Implementations

impl Clone for TemplateParameter

fn clone(&self) -> TemplateParameter

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TemplateParameter

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

Formats the value using the given formatter.

impl Default for TemplateParameter

fn default() -> Self

Returns the “default value” for a type.

impl Message for TemplateParameter

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 TemplateParameter

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