Struct RowSelector 

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

RowSelector represents a consecutive range of rows to either select or skip when scanning an ORC file.

A RowSelector is a building block of RowSelection.

Fields

row_count: usize

The number of rows

skip: bool

If true, skip row_count rows; otherwise select them

Implementations

impl RowSelector

pub fn select(row_count: usize) -> Self

Create a selector to select row_count rows

pub fn skip(row_count: usize) -> Self

Create a selector to skip row_count rows

Trait Implementations

impl Clone for RowSelector

fn clone(&self) -> RowSelector

Returns a duplicate 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

Tests for self and other values to be equal, and is used by ==.

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

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