Struct ExtScalarValue

Source

pub struct ExtScalarValue<V: ExtVTable>(/* private fields */);

Expand description

A typed extension scalar value, parameterized by a concrete ExtVTable.

This is the extension scalar analog of ExtDType<V>: it retains full type information about the vtable, providing direct access to the vtable and storage value without downcasting.

You can construct one of these via try_new() from an ExtDType<V> and a storage ScalarValue, and erase the type with erased() to obtain an ExtScalarValueRef.

Implementations§

Source §

impl<V: ExtVTable> ExtScalarValue<V>

Source

pub fn try_new( ext_dtype: &ExtDType<V>, storage: ScalarValue, ) -> VortexResult<Self>

Creates a new extension scalar from a storage ScalarValue, validating it against the given ExtDType.

§Errors

Returns an error if ExtVTable::validate_scalar_value fails for the given storage value and extension dtype.

Source

pub fn erased(self) -> ExtScalarValueRef

Erases the concrete type information, returning a type-erased ExtScalarValueRef.

Source

pub fn id(&self) -> ExtId

Returns the ExtId identifying this extension scalar’s type.

Source

pub fn vtable(&self) -> &V

Returns a reference to the ExtVTable for this extension scalar.

Source

pub fn storage_value(&self) -> &ScalarValue

Returns a reference to the underlying storage ScalarValue.
