Struct ColumnMetadata 

#[non_exhaustive]
pub struct ColumnMetadata {
    pub column: String,
    pub field_path: String,
    pub function_name: String,
    pub function_module: String,
    pub data_source: DataSource,

}

Metadata of the column.

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.

column: String

Name of the column.

field_path: String

Field path of the queried field, if any.

function_name: String

Name of the function used to query the field, if any.

function_module: String

Module of the function used to query the field, if any.

data_source: DataSource

Data source queried.

timestamp_metadata: Option<TimestampMetadata>

Timestamp Metadata

longitude: bool

Whether the column is a longitude field.

latitude: bool

Whether the column is a latitude field.

selected: bool

Whether the column is selected in the final response.

unselected: bool

Whether the column is unselected in the final response.

Implementations

impl ColumnMetadata

pub fn new() -> Self

Creates a new default instance.

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

Sets the value of column.

Example

let x = ColumnMetadata::new().set_column("example");

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

Sets the value of field_path.

Example

let x = ColumnMetadata::new().set_field_path("example");

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

Sets the value of function_name.

Example

let x = ColumnMetadata::new().set_function_name("example");

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

Sets the value of function_module.

Example

let x = ColumnMetadata::new().set_function_module("example");

pub fn set_data_source<T: Into<DataSource>>(self, v: T) -> Self

Sets the value of data_source.

Example

use google_cloud_chronicle_v1::model::DataSource;
let x0 = ColumnMetadata::new().set_data_source(DataSource::Udm);
let x1 = ColumnMetadata::new().set_data_source(DataSource::Entity);
let x2 = ColumnMetadata::new().set_data_source(DataSource::IngestionMetrics);

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

where T: Into<TimestampMetadata>,

Sets the value of timestamp_metadata.

Example

use google_cloud_chronicle_v1::model::TimestampMetadata;
let x = ColumnMetadata::new().set_timestamp_metadata(TimestampMetadata::default()/* use setters */);

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

where T: Into<TimestampMetadata>,

Sets or clears the value of timestamp_metadata.

Example

use google_cloud_chronicle_v1::model::TimestampMetadata;
let x = ColumnMetadata::new().set_or_clear_timestamp_metadata(Some(TimestampMetadata::default()/* use setters */));
let x = ColumnMetadata::new().set_or_clear_timestamp_metadata(None::<TimestampMetadata>);

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

Sets the value of longitude.

Example

let x = ColumnMetadata::new().set_longitude(true);

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

Sets the value of latitude.

Example

let x = ColumnMetadata::new().set_latitude(true);

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

Sets the value of selected.

Example

let x = ColumnMetadata::new().set_selected(true);

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

Sets the value of unselected.

Example

let x = ColumnMetadata::new().set_unselected(true);

Trait Implementations

impl Clone for ColumnMetadata

fn clone(&self) -> ColumnMetadata

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ColumnMetadata

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

Formats the value using the given formatter.

impl Default for ColumnMetadata

fn default() -> ColumnMetadata

Returns the “default value” for a type.

impl Message for ColumnMetadata

fn typename() -> &'static str

The typename of this message.

impl PartialEq for ColumnMetadata

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