[−][src]Struct arrow::record_batch::RecordBatch

pub struct RecordBatch { /* fields omitted */ }

A batch of column-oriented data

Methods

impl RecordBatch[src]

pub fn try_new(schema: Arc<Schema>, columns: Vec<ArrayRef>) -> Result<Self>[src]

Creates a RecordBatch from a schema and columns

Expects the following:

  • the vec of columns to not be empty
  • the schema and column data types to have equal lengths and match
  • each array in columns to have the same length

pub fn schema(&self) -> &Arc<Schema>[src]

Returns the schema of the record batch

pub fn num_columns(&self) -> usize[src]

Number of columns in the record batch

pub fn num_rows(&self) -> usize[src]

Number of rows in each column

pub fn column(&self, i: usize) -> &ArrayRef[src]

Get a reference to a column's array by index

pub fn columns(&self) -> &[ArrayRef][src]

Get a reference to all columns
