Struct OpaqueEncoding

pub struct OpaqueEncoding(pub u16);

An encoding of an array that we cannot interpret.

Vortex allows for pluggable encodings. This can lead to issues when one process produces a file using a custom encoding, and then another process without knowledge of the encoding attempts to read it.

OpaqueEncoding allows deserializing these arrays. Many common operations will fail, but it allows deserialization and introspection in a type-erased manner on the children and metadata.

We hold the original 16-bit encoding ID for producing helpful error messages.

Trait Implementations

impl Clone for OpaqueEncoding

fn clone(&self) -> OpaqueEncoding

Returns a copy of the value.

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

Performs copy-assignment from source.

impl ComputeVTable for OpaqueEncoding

fn binary_boolean_fn( &self, _lhs: &ArrayData, _rhs: &ArrayData, ) -> Option<&dyn BinaryBooleanFn<ArrayData>>

Implementation of binary boolean logic operations.

fn cast_fn(&self) -> Option<&dyn CastFn<ArrayData>>

Implemented for arrays that can be casted to different types.

fn compare_fn(&self) -> Option<&dyn CompareFn<ArrayData>>

Binary operator implementation for arrays against other arrays.

fn fill_forward_fn(&self) -> Option<&dyn FillForwardFn<ArrayData>>

Array function that returns new arrays a non-null value is repeated across runs of nulls.

fn filter_fn(&self) -> Option<&dyn FilterFn<ArrayData>>
