    ElementAndArray,
    ArrayAndIndex,
    ArrayAndElementAndOptionalIndex,
    Array,
    MapArray,
}

Variants

ArrayAndElement

Specialized Signature for ArrayAppend and similar functions The first argument should be List/LargeList/FixedSizedList, and the second argument should be non-list or list. The second argument’s list dimension should be one dimension less than the first argument’s list dimension. List dimension of the List/LargeList is equivalent to the number of List. List dimension of the non-list is 0.

ElementAndArray

Specialized Signature for ArrayPrepend and similar functions The first argument should be non-list or list, and the second argument should be List/LargeList. The first argument’s list dimension should be one dimension less than the second argument’s list dimension.

ArrayAndIndex

Specialized Signature for Array functions of the form (List/LargeList, Index) The first argument should be List/LargeList/FixedSizedList, and the second argument should be Int64.

ArrayAndElementAndOptionalIndex

Specialized Signature for Array functions of the form (List/LargeList, Element, Optional Index)

Array

Specialized Signature for ArrayEmpty and similar functions The function takes a single argument that must be a List/LargeList/FixedSizeList or something that can be coerced to one of those types.

MapArray

Specialized Signature for MapArray The function takes a single argument that must be a MapArray

Trait Implementations

impl Clone for ArrayFunctionSignature

fn clone(&self) -> ArrayFunctionSignature

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ArrayFunctionSignature

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

Formats the value using the given formatter.

impl Display for ArrayFunctionSignature

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

Formats the value using the given formatter.

impl Hash for ArrayFunctionSignature

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ArrayFunctionSignature

fn eq(&self, other: &ArrayFunctionSignature) -> 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 PartialOrd for ArrayFunctionSignature

fn partial_cmp(&self, other: &ArrayFunctionSignature) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
