Enum google_cloud_bigquery::http::routine::DeterminismLevel

pub enum DeterminismLevel {
    DeterminismLevelUnspecified,
    Deterministic,
    NotDeterministic,
}

JavaScript UDF determinism levels. If all JavaScript UDFs are DETERMINISTIC, the query result is potentially cachable (see below). If any JavaScript UDF is NOT_DETERMINISTIC, the query result is not cacheable. Even if a JavaScript UDF is deterministic, many other factors can prevent usage of cached query results. Example factors include but not limited to: DDL/DML, non-deterministic SQL function calls, update of referenced tables/views/UDFs or imported JavaScript libraries. SQL UDFs cannot have determinism specified. Their determinism is automatically determined.

Trait Implementations

impl Clone for DeterminismLevel

fn clone(&self) -> DeterminismLevel

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DeterminismLevel

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

Formats the value using the given formatter.

impl Default for DeterminismLevel

fn default() -> DeterminismLevel

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for DeterminismLevel

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for DeterminismLevel

fn eq(&self, other: &DeterminismLevel) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for DeterminismLevel

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for DeterminismLevel

impl StructuralPartialEq for DeterminismLevel
