Struct Declaration 

#[non_exhaustive]
pub struct Declaration {
    pub relation_descriptor: Option<RelationDescriptor>,
    /* private fields */
}

Represents a relation which is not managed by Dataform but which may be referenced by Dataform actions.

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.

relation_descriptor: Option<RelationDescriptor>

Descriptor for the relation and its columns. Used as documentation only, i.e. values here will result in no changes to the relation’s metadata.

Implementations

impl Declaration

pub fn new() -> Self

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

where T: Into<RelationDescriptor>,

Sets the value of relation_descriptor.

Example

use google_cloud_dataform_v1::model::RelationDescriptor;
let x = Declaration::new().set_relation_descriptor(RelationDescriptor::default()/* use setters */);

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

where T: Into<RelationDescriptor>,

Sets or clears the value of relation_descriptor.

Example

use google_cloud_dataform_v1::model::RelationDescriptor;
let x = Declaration::new().set_or_clear_relation_descriptor(Some(RelationDescriptor::default()/* use setters */));
let x = Declaration::new().set_or_clear_relation_descriptor(None::<RelationDescriptor>);

Trait Implementations

impl Clone for Declaration

fn clone(&self) -> Declaration

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Declaration

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

Formats the value using the given formatter.

impl Default for Declaration

fn default() -> Declaration

Returns the “default value” for a type.

impl Message for Declaration

fn typename() -> &'static str

The typename of this message.

impl PartialEq for Declaration

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