Struct Schema 

#[non_exhaustive]
pub struct Schema {
    pub user_managed: bool,
    pub fields: Vec<SchemaField>,
    pub partition_fields: Vec<PartitionField>,
    pub partition_style: PartitionStyle,
    /* private fields */
}

Schema information describing the structure and layout of the data.

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.

user_managed: bool

Required. Set to true if user-managed or false if managed by Dataplex Universal Catalog. The default is false (managed by Dataplex Universal Catalog).

• Set to falseto enable Dataplex Universal Catalog discovery to update the schema. including new data discovery, schema inference, and schema evolution. Users retain the ability to input and edit the schema. Dataplex Universal Catalog treats schema input by the user as though produced by a previous Dataplex Universal Catalog discovery operation, and it will evolve the schema and take action based on that treatment.

• Set to true to fully manage the entity schema. This setting guarantees that Dataplex Universal Catalog will not change schema fields.

fields: Vec<SchemaField>

Optional. The sequence of fields describing data in table entities. Note: BigQuery SchemaFields are immutable.

partition_fields: Vec<PartitionField>

Optional. The sequence of fields describing the partition structure in entities. If this field is empty, there are no partitions within the data.

partition_style: PartitionStyle

Optional. The structure of paths containing partition data within the entity.

Implementations

impl Schema

pub fn new() -> Self

Creates a new default instance.

pub fn set_user_managed<T: Into<bool>>(self, v: T) -> Self

Sets the value of user_managed.

Example

let x = Schema::new().set_user_managed(true);

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

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

Sets the value of fields.

Example

use google_cloud_dataplex_v1::model::schema::SchemaField;
let x = Schema::new()
    .set_fields([
        SchemaField::default()/* use setters */,
        SchemaField::default()/* use (different) setters */,
    ]);

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

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

Sets the value of partition_fields.

Example

use google_cloud_dataplex_v1::model::schema::PartitionField;
let x = Schema::new()
    .set_partition_fields([
        PartitionField::default()/* use setters */,
        PartitionField::default()/* use (different) setters */,
    ]);

pub fn set_partition_style<T: Into<PartitionStyle>>(self, v: T) -> Self

Sets the value of partition_style.

Example

use google_cloud_dataplex_v1::model::schema::PartitionStyle;
let x0 = Schema::new().set_partition_style(PartitionStyle::HiveCompatible);
