Struct PlaceholderVectorFunctionTaskExpression 

pub struct PlaceholderVectorFunctionTaskExpression {
    pub input_schema: InputSchema,
    pub output_length: Expression,
    pub input_split: Expression,
    pub input_merge: Expression,
    pub skip: Option<Expression>,
    pub map: Option<Expression>,
    pub input: WithExpression<InputValueExpression>,
    pub output: Expression,
}

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

Like VectorFunctionTaskExpression but without owner/repository/commit. Always produces an equalized vector of length output_length.

Fields

input_schema: InputSchema

JSON Schema defining the expected input structure.

output_length: Expression

Expression computing the expected output vector length. Receives: input.

input_split: Expression

Expression transforming input into sub-inputs for swiss system. Receives: input.

input_merge: Expression

Expression merging sub-inputs back into one input. Receives: input (as an array).

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 placeholder function. Receives: input, map (if mapped).

output: Expression

Expression to transform the equalized vector output. Receives: input, output as Vector(equalized).

Implementations

impl PlaceholderVectorFunctionTaskExpression

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

Trait Implementations

impl<'arbitrary> Arbitrary<'arbitrary> for PlaceholderVectorFunctionTaskExpression

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 PlaceholderVectorFunctionTaskExpression

fn clone(&self) -> PlaceholderVectorFunctionTaskExpression

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PlaceholderVectorFunctionTaskExpression

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for PlaceholderVectorFunctionTaskExpression

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for PlaceholderVectorFunctionTaskExpression

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 PlaceholderVectorFunctionTaskExpression

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
