Implementations§

Source§

impl DataBatch

Source

pub fn from_data_vec_for_type( data_type: &NautilusDataType, data: Vec<Data>, ) -> Result<Self>

Converts owned compatibility rows into a typed batch for data_type.

This is a transition path for backends that still decode through Data but should not expose legacy batches to typed replay.

§Errors

Returns an error if data_type is not replayable as a typed batch.

Source

pub fn from_data_vec_grouped(data: &[Data]) -> Result<Vec<Self>>

Groups mixed compatibility rows into typed batches.

Data::BookDeltas values retain their event-batch boundary in a separate typed batch.

§Errors

Returns an error if a row cannot be represented by a typed batch.

Source

pub fn len(&self) -> usize

Source

pub fn is_empty(&self) -> bool

Source

pub fn data_type_name(&self) -> &'static str

Returns the storage-family name of this batch’s data type.

Source

pub fn is_monotonically_increasing_by_init(&self) -> bool

Source

pub fn get(&self, index: usize) -> Option<DataRef<'_>>

Source

pub fn aligned_chunk( &self, start: usize, chunk_size: Option<usize>, ) -> Option<(Self, usize)>

Source

pub fn slice(&self, start: usize, end: usize) -> Self
