Struct ViewVersion

pub struct ViewVersion { /* private fields */ }

A view versions represents the definition of a view at a specific point in time.

Implementations

impl ViewVersion

pub fn builder() -> ViewVersionBuilder<((), (), (), (), (), (), ())>

Create a builder for building ViewVersion. On the builder, call .version_id(...)(optional), .schema_id(...), .timestamp_ms(...), .summary(...)(optional), .representations(...), .default_catalog(...)(optional), .default_namespace(...) to set the values of the fields. Finally, call .build() to create the instance of ViewVersion.

impl ViewVersion

pub fn version_id(&self) -> ViewVersionId

Get the version id of this view version.

pub fn schema_id(&self) -> SchemaId

Get the schema id of this view version.

pub fn timestamp(&self) -> Result<DateTime<Utc>>

Get the timestamp of when the view version was created

pub fn timestamp_ms(&self) -> i64

Get the timestamp of when the view version was created in milliseconds since epoch

pub fn summary(&self) -> &HashMap<String, String>

Get summary of the view version

pub fn representations(&self) -> &ViewRepresentations

Get this views representations

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

Get the default catalog for this view version

pub fn default_namespace(&self) -> &NamespaceIdent

Get the default namespace to use when a reference in the SELECT is a single identifier

pub fn schema(&self, view_metadata: &ViewMetadata) -> Result<SchemaRef>

Get the schema of this snapshot.

pub fn with_version_id(self, version_id: i32) -> Self

Change the version id of this view version.

pub fn with_schema_id(self, schema_id: SchemaId) -> Self

Change the schema id of this view version.

Trait Implementations

impl Clone for ViewVersion

fn clone(&self) -> ViewVersion

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ViewVersion

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ViewVersion

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ViewVersion

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

impl Serialize for ViewVersion

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
