Struct StableRow 

pub struct StableRow(pub Row);

A Row that serializes as protobuf-encoded ProtoRow bytes.

Row’s own serde impl emits the raw bytes of the in-memory Tag based datum encoding, which is free to change between releases. Use this wrapper instead wherever a row is serialized into a durable, cross-version format, such as the stable LIR plan format. ProtoRow already carries the needed backward compatibility obligation: it is persist’s storage codec for SourceData, and row.proto is covered by the buf breaking lint.

Tuple Fields

0: Row

Methods from Deref<Target = Row>

pub fn byte_len(&self) -> usize

Returns the total amount of bytes used by this row.

pub fn data_len(&self) -> usize

The length of the encoded row in bytes. Does not include the size of the Row struct itself.

pub fn byte_capacity(&self) -> usize

Returns the total capacity in bytes used by this row.

pub fn as_row_ref(&self) -> &RowRef

Extracts a Row slice containing the entire Row.

Methods from Deref<Target = RowRef>

pub fn unpack(&self) -> Vec<Datum<'_>>

Unpack self into a Vec<Datum> for efficient random access.

pub fn unpack_first(&self) -> Datum<'_>

Return the first Datum in self

Panics if the RowRef is empty.

pub fn iter(&self) -> DatumListIter<'_>

Iterate the Datum elements of the RowRef.

pub fn byte_len(&self) -> usize

Return the byte length of this RowRef.

pub fn data(&self) -> &[u8]

For debugging only.

pub fn is_empty(&self) -> bool

True iff there is no data in this RowRef.
