Enum TaskExpression 

pub enum TaskExpression {
    ScalarFunction(ScalarFunctionTaskExpression),
    VectorFunction(VectorFunctionTaskExpression),
    VectorCompletion(VectorCompletionTaskExpression),
    PlaceholderScalarFunction(PlaceholderScalarFunctionTaskExpression),
    PlaceholderVectorFunction(PlaceholderVectorFunctionTaskExpression),
}

A task definition with expressions (pre-compilation).

Task expressions contain dynamic fields (JMESPath or Starlark) that are resolved against input data during compilation. Use compile to produce a concrete Task.

Variants

ScalarFunction(ScalarFunctionTaskExpression)

VectorFunction(VectorFunctionTaskExpression)

VectorCompletion(VectorCompletionTaskExpression)

PlaceholderScalarFunction(PlaceholderScalarFunctionTaskExpression)

PlaceholderVectorFunction(PlaceholderVectorFunctionTaskExpression)

Implementations

impl TaskExpression

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

pub fn take_skip(&mut self) -> Option<Expression>

Takes and returns the skip expression, if present.

pub fn map(&self) -> Option<&Expression>

Returns the map expression, if this is a mapped task.

pub fn compile(self, params: &Params<'_, '_>) -> Result<Task, ExpressionError>

Compiles the expression into a concrete Task.

Trait Implementations

impl<'arbitrary> Arbitrary<'arbitrary> for TaskExpression

fn arbitrary(u: &mut Unstructured<'arbitrary>) -> Result<Self>

Generate an arbitrary value of Self from the given unstructured data.

fn arbitrary_take_rest(u: Unstructured<'arbitrary>) -> Result<Self>

Generate an arbitrary value of Self from the entirety of the given unstructured data.

fn size_hint(depth: usize) -> (usize, Option<usize>)

Get a size hint for how many bytes out of an Unstructured this type needs to construct itself.

fn try_size_hint( depth: usize, ) -> Result<(usize, Option<usize>), MaxRecursionReached>

Get a size hint for how many bytes out of an Unstructured this type needs to construct itself.

impl Clone for TaskExpression

fn clone(&self) -> TaskExpression

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TaskExpression

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for TaskExpression

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for TaskExpression

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

impl PartialEq for TaskExpression

fn eq(&self, other: &TaskExpression) -> 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 TaskExpression

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
