Struct parquet::arrow::arrow_reader::RowSelector

pub struct RowSelector {
    pub row_count: usize,
    pub skip: bool,
}

RowSelection is a collection of RowSelector used to skip rows when scanning a parquet file

Fields

row_count: usize

The number of rows

skip: bool

If true, skip row_count rows

Implementations

impl RowSelector

pub fn select(row_count: usize) -> Self

Select row_count rows

pub fn skip(row_count: usize) -> Self

Skip row_count rows

Trait Implementations

impl Clone for RowSelector

fn clone(&self) -> RowSelector

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for RowSelector

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl FromIterator<RowSelector> for RowSelection

fn from_iter<T: IntoIterator<Item = RowSelector>>(iter: T) -> Self

Creates a value from an iterator.

impl PartialEq for RowSelector

fn eq(&self, other: &RowSelector) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
