Struct DataTableColumnInfo 

#[non_exhaustive]
pub struct DataTableColumnInfo {
    pub column_index: i32,
    pub original_column: String,
    pub key_column: bool,
    pub repeated_values: bool,
    pub path_or_type: Option<PathOrType>,
    /* private fields */
}

DataTableColumnInfo represents the column metadata of the datatable. The column_index represents the ordering of the values in DataTableRow.

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_index: i32

Required. Column Index. 0,1,2…

original_column: String

Required. Original column name of the Data Table (present in the CSV header in case of creation of data tables using file uploads). It must satisfy the following requirements:

• Starts with letter.
• Contains only letters, numbers and underscore.
• Must be unique and has length < 256.

key_column: bool

Optional. Whether to include this column in the calculation of the row ID. If no columns have key_column = true, all columns will be included in the calculation of the row ID.

repeated_values: bool

Optional. Whether the column is a repeated values column.

path_or_type: Option<PathOrType>

Implementations

impl DataTableColumnInfo

pub fn new() -> Self

Creates a new default instance.

pub fn set_column_index<T: Into<i32>>(self, v: T) -> Self

Sets the value of column_index.

Example

let x = DataTableColumnInfo::new().set_column_index(42);

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

Sets the value of original_column.

Example

let x = DataTableColumnInfo::new().set_original_column("example");

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

Sets the value of key_column.

Example

let x = DataTableColumnInfo::new().set_key_column(true);

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

Sets the value of repeated_values.

Example

let x = DataTableColumnInfo::new().set_repeated_values(true);

pub fn set_path_or_type<T: Into<Option<PathOrType>>>(self, v: T) -> Self

Sets the value of path_or_type.

Note that all the setters affecting path_or_type are mutually exclusive.

Example

use google_cloud_chronicle_v1::model::data_table_column_info::PathOrType;
let x = DataTableColumnInfo::new().set_path_or_type(Some(PathOrType::MappedColumnPath("example".to_string())));

pub fn mapped_column_path(&self) -> Option<&String>

The value of path_or_type if it holds a MappedColumnPath, None if the field is not set or holds a different branch.

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

Sets the value of path_or_type to hold a MappedColumnPath.

Note that all the setters affecting path_or_type are mutually exclusive.

Example

let x = DataTableColumnInfo::new().set_mapped_column_path("example");
assert!(x.mapped_column_path().is_some());
assert!(x.column_type().is_none());

pub fn column_type(&self) -> Option<&DataTableColumnType>

The value of path_or_type if it holds a ColumnType, None if the field is not set or holds a different branch.

pub fn set_column_type<T: Into<DataTableColumnType>>(self, v: T) -> Self

Sets the value of path_or_type to hold a ColumnType.

Note that all the setters affecting path_or_type are mutually exclusive.

Example

use google_cloud_chronicle_v1::model::data_table_column_info::DataTableColumnType;
let x0 = DataTableColumnInfo::new().set_column_type(DataTableColumnType::String);
let x1 = DataTableColumnInfo::new().set_column_type(DataTableColumnType::Regex);
let x2 = DataTableColumnInfo::new().set_column_type(DataTableColumnType::Cidr);
assert!(x0.column_type().is_some());
assert!(x0.mapped_column_path().is_none());
assert!(x1.column_type().is_some());
assert!(x1.mapped_column_path().is_none());
assert!(x2.column_type().is_some());
assert!(x2.mapped_column_path().is_none());

Trait Implementations

impl Clone for DataTableColumnInfo

fn clone(&self) -> DataTableColumnInfo

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DataTableColumnInfo

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

Formats the value using the given formatter.

impl Default for DataTableColumnInfo

fn default() -> DataTableColumnInfo

Returns the “default value” for a type.

impl Message for DataTableColumnInfo

fn typename() -> &'static str

The typename of this message.

impl PartialEq for DataTableColumnInfo

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