Struct LazyDType

pub struct LazyDType { /* private fields */ }

Implementations

impl LazyDType

pub unsafe fn from_schema_bytes(dtype_bytes: Bytes) -> Self

Create a LazilyDeserializedDType from a flatbuffer schema bytes i.e., these bytes need to be deserializable as message::Schema

Safety

This function is unsafe because it trusts the caller to pass in a valid flatbuffer representing a message::Schema.

pub fn from_dtype(dtype: DType) -> Self

pub fn unknown() -> Self

pub fn project(&self, fields: &[Field]) -> VortexResult<Arc<Self>>

Restrict the underlying dtype to selected fields

pub fn field(&self, field: &Field) -> VortexResult<Arc<Self>>

Extract single field out of this dtype

pub fn names(&self) -> VortexResult<FieldNames>

Extract field names from the underlying dtype if there are any

pub fn value(&self) -> VortexResult<&DType>

Get vortex dtype out of serialized bytes
