pub struct ColumnWriterImpl<T: DataType> { /* fields omitted */ }
Typed column writer for a primitive column.
Writes batch of values, definition levels and repetition levels.
Returns number of values processed (written).
If definition and repetition levels are provided, we write fully those levels and
select how many values to write (this number will be returned), since number of
actual written values may be smaller than provided values.
If only values are provided, then all values are written and the length of
of the values buffer is returned.
Definition and/or repetition levels can be omitted, if values are
non-nullable and/or non-repeated.
Returns total number of bytes written by this column writer so far.
This value is also returned when column writer is closed.
Returns total number of rows written by this column writer so far.
This value is also returned when column writer is closed.
Finalises writes and closes the column writer.
Returns total bytes written, total rows written and column chunk metadata.

Create an error for a missing method specialization. Defaults to panicking with type, trait & method names. S
is the encoder/decoder state type, T
is the type being encoded/decoded, and the arguments are the names of the trait and method that should've been overridden. Read more
