Struct DuckDbStruct

.NET representation of an instance of a structure type from DuckDB, where the member values are boxed.

Implements

ITuple

Inherited Members

ValueType.Equals(object)

ValueType.GetHashCode()

ValueType.ToString()

object.Equals(object, object)

object.GetType()

object.ReferenceEquals(object, object)

Namespace: Mallard.Types

Assembly: Mallard.dll

Syntax

public readonly struct DuckDbStruct : ITuple

Remarks

This representation is inefficient because of the boxing, but avoids generics (of arbitrary arity).

Instances of this type are intended to be immutable (once created), but if the type of a member is a reference type, or a mutable value type (i.e. not readonly in C#), user code may be able to mutate the member value through the object reference that is made available (even in safe code). It is, obviously, highly discouraged to do so, but no direct memory corruption will occur should that be attempted.

Properties

this[int]

Get a member of the structure by its index.

Declaration

public object? this[int index] { get; }

Parameters

Length

The number of members in the structure.

Declaration

public int Length { get; }

Property Value

Type	Description
int

Methods

ToImmutableArray()

Get the values of the members of the structure as an immutable array of boxed objects.

Declaration

public ImmutableArray<object?> ToImmutableArray()

Returns

Type	Description
ImmutableArray<object>
