def extract(*indices)
	indices_ptr = FFI::MemoryPointer.new(:uint, indices.length)
	indices_ptr.write_array_of_uint(indices)
	
	ConstantExpr.new(Bindings.const_extract_value(@ptr, indices_ptr, indices.length))
end

#insert(value, indices) ⇒ ConstantExpr

Insert values into a constant aggregate value.

Parameters:

  • value (Value) —

    Value to insert.

  • indices (Array<Value>) —

    Array of values representing indices into the aggregate.

Returns:

  • (ConstantExpr) —

    New aggregate representation with inserted values.
