Struct PlaceholderScalarFunctionTask 

pub struct PlaceholderScalarFunctionTask {
    pub input_schema: InputSchema,
    pub input: InputValue,
    pub output: Expression,
}

A compiled placeholder scalar function task.

Always produces Scalar(0.5) before the output expression is applied.

Fields

input_schema: InputSchema

JSON Schema defining the expected input structure.

input: InputValue

The resolved input.

output: Expression

Expression to transform the fixed 0.5 output.

Implementations

impl PlaceholderScalarFunctionTask

pub fn compile_output( &self, input: &InputValue, raw_output: TaskOutput<'_>, ) -> Result<TaskOutputOwned, ExpressionError>

Trait Implementations

impl Clone for PlaceholderScalarFunctionTask

fn clone(&self) -> PlaceholderScalarFunctionTask

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PlaceholderScalarFunctionTask

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for PlaceholderScalarFunctionTask

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for PlaceholderScalarFunctionTask

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 PlaceholderScalarFunctionTask

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
