Struct csv_async::Position

source ·
pub struct Position { /* private fields */ }
Expand description

A position in CSV data.

A position is used to report errors in CSV data. All positions include the byte offset, line number and record index at which the error occurred.

Byte offsets and record indices start at 0. Line numbers start at 1.

A CSV reader will automatically assign the position of each record.

Implementations§

source§

impl Position

source

pub fn new() -> Position

Returns a new position initialized to the start value.

source

pub fn byte(&self) -> u64

The byte offset, starting at 0, of this position.

source

pub fn line(&self) -> u64

The line number, starting at 1, of this position.

source

pub fn record(&self) -> u64

The record index, starting with the first record at 0.

source

pub fn set_byte(&mut self, byte: u64) -> &mut Position

Set the byte offset of this position.

source

pub fn set_line(&mut self, line: u64) -> &mut Position

Set the line number of this position.

If the line number is less than 1, then this method panics.

source

pub fn set_record(&mut self, record: u64) -> &mut Position

Set the record index of this position.

impl PartialEq for Position

source§

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

1.0.0 · source§

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.
