Struct FallbackEncoder

struct FallbackEncoder {
    encoder: FallbackEncoderImpl,
    num_values: usize,
    variable_length_bytes: i64,
}

A fallback encoder, i.e. non-dictionary, for ByteArray

Fields

encoder: FallbackEncoderImpl

num_values: usize

variable_length_bytes: i64

Implementations

impl FallbackEncoder

fn new(descr: &ColumnDescPtr, props: &WriterProperties) -> Result<Self>

Create the fallback encoder for the given ColumnDescPtr and WriterProperties

fn encode<T>(&mut self, values: T, indices: &[usize])

where T: ArrayAccessor + Copy, T::Item: AsRef<[u8]>,

Encode values to the in-progress page

fn estimated_data_page_size(&self) -> usize

Returns an estimate of the data page size in bytes

This includes: <already_written_encoded_byte_size> + <estimated_encoded_size_of_unflushed_bytes>

fn flush_data_page( &mut self, min_value: Option<ByteArray>, max_value: Option<ByteArray>, ) -> Result<DataPageValues<ByteArray>>
