}

Dynamically typed trait for invoking array vtables.

Required Methods

fn as_any(&self) -> &dyn Any

Downcast the encoding to Any.

fn id(&self) -> ArrayId

Returns the ID of the encoding.

fn build( &self, dtype: &DType, len: usize, metadata: &[u8], buffers: &[BufferHandle], children: &dyn ArrayChildren, ) -> VortexResult<ArrayRef>

Build an array from its parts.

fn with_children( &self, array: &dyn Array, children: &dyn ArrayChildren, ) -> VortexResult<ArrayRef>

fn encode( &self, input: &Canonical, like: Option<&dyn Array>, ) -> VortexResult<Option<ArrayRef>>

Encode the canonical array into this encoding implementation. Returns None if this encoding does not support the given canonical array, for example if the data type is incompatible.

Panics if like is encoded with a different encoding.

Implementations

impl dyn DynVTable + '_

pub fn as_<V: VTable>(&self) -> &V

Trait Implementations

impl Display for dyn DynVTable + '_

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

Formats the value using the given formatter.

impl PartialEq for dyn DynVTable + '_

fn eq(&self, other: &Self) -> 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.
