Struct RelationDescriptor 

#[non_exhaustive]
pub struct RelationDescriptor {
    pub description: String,
    pub columns: Vec<ColumnDescriptor>,
    pub bigquery_labels: HashMap<String, String>,
    /* private fields */
}

Describes a relation and its columns.

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.

description: String

A text description of the relation.

columns: Vec<ColumnDescriptor>

A list of descriptions of columns within the relation.

bigquery_labels: HashMap<String, String>

A set of BigQuery labels that should be applied to the relation.

Implementations

impl RelationDescriptor

pub fn new() -> Self

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

Sets the value of description.

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

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

Sets the value of columns.

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

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

Sets the value of bigquery_labels.

Trait Implementations

impl Clone for RelationDescriptor

fn clone(&self) -> RelationDescriptor

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RelationDescriptor

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

Formats the value using the given formatter.

impl Default for RelationDescriptor

fn default() -> RelationDescriptor

Returns the “default value” for a type.

impl Message for RelationDescriptor

fn typename() -> &'static str

The typename of this message.

impl PartialEq for RelationDescriptor

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