Struct VectorFunctionTaskExpression 

pub struct VectorFunctionTaskExpression {
    pub path: RemotePath,
    pub skip: Option<Expression>,
    pub map: Option<Expression>,
    pub input: WithExpression<InputValueExpression>,
    pub output: Expression,
}

Expression for a task that calls a vector function (pre-compilation).

Fields

path: RemotePath

skip: Option<Expression>

If this expression evaluates to true, skip the task. Receives: input.

map: Option<Expression>

Expression that evaluates to the number of mapped task instances. Each instance receives map as an integer index (0-based).

input: WithExpression<InputValueExpression>

Expression for the input to pass to the function. Receives: input, map (if mapped).

output: Expression

Expression to transform the task result into a valid function output.

Receives output which is one of 4 variants:

• Scalar(Decimal) - a single score
• Vector(Vec<Decimal>) - a vector of scores
• Vectors(Vec<Vec<Decimal>>) - multiple vectors (from mapped tasks)
• Err(Value) - an error

The expression must return a TaskOutputOwned that is valid for the parent function’s type:

• For scalar functions: must return Scalar(value) where value is in [0, 1]
• For vector functions: must return Vector(values) where values sum to ~1 and match the expected length

The function’s final output is computed as a weighted average of all task outputs using profile weights. If a function has only one task, that task’s output becomes the function’s output directly.

Implementations

impl VectorFunctionTaskExpression

pub fn url(&self) -> String

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

Compiles the expression into a concrete VectorFunctionTask.

Trait Implementations

impl<'arbitrary> Arbitrary<'arbitrary> for VectorFunctionTaskExpression

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 VectorFunctionTaskExpression

fn clone(&self) -> VectorFunctionTaskExpression

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for VectorFunctionTaskExpression

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for VectorFunctionTaskExpression

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for VectorFunctionTaskExpression

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 VectorFunctionTaskExpression

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
