Struct TemplateParameter 

#[non_exhaustive]
pub struct TemplateParameter {
    pub name: String,
    pub fields: Vec<String>,
    pub description: String,
    pub validation: Option<ParameterValidation>,
    /* private fields */
}

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 (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

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. 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.

Implementations

impl TemplateParameter

pub fn new() -> Self

Creates a new default instance.

pub fn set_name<T: Into<String>>(self, v: T) -> Self

Sets the value of name.

Example

let x = TemplateParameter::new().set_name("example");

pub fn set_fields<T, V>(self, v: T) -> Self

where T: IntoIterator<Item = V>, V: Into<String>,

Sets the value of fields.

Example

let x = TemplateParameter::new().set_fields(["a", "b", "c"]);

pub fn set_description<T: Into<String>>(self, v: T) -> Self

Sets the value of description.

Example

let x = TemplateParameter::new().set_description("example");

pub fn set_validation<T>(self, v: T) -> Self

where T: Into<ParameterValidation>,

Sets the value of validation.

Example

use google_cloud_dataproc_v1::model::ParameterValidation;
let x = TemplateParameter::new().set_validation(ParameterValidation::default()/* use setters */);

pub fn set_or_clear_validation<T>(self, v: Option<T>) -> Self

where T: Into<ParameterValidation>,

Sets or clears the value of validation.

Example

use google_cloud_dataproc_v1::model::ParameterValidation;
let x = TemplateParameter::new().set_or_clear_validation(Some(ParameterValidation::default()/* use setters */));
let x = TemplateParameter::new().set_or_clear_validation(None::<ParameterValidation>);
