Struct ParsePosition 

pub struct ParsePosition { /* private fields */ }

One-based line/column context plus the byte offset for a parse error.

Implementations

impl ParsePosition

pub const fn new(offset: usize, line: usize, column: usize) -> ParsePosition

Creates a new parse position.

offset is zero-based and counts bytes from the parsed input after any parser-specific pre-processing, while line and column are one-based.

pub const fn offset(self) -> usize

Returns the zero-based byte offset in the parsed input.

pub const fn line(self) -> usize

Returns the one-based line number.

pub const fn column(self) -> usize

Returns the one-based column number.

Trait Implementations

impl Clone for ParsePosition

fn clone(&self) -> ParsePosition

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ParsePosition

impl Debug for ParsePosition

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

Formats the value using the given formatter.

impl Eq for ParsePosition

impl PartialEq for ParsePosition

fn eq(&self, other: &ParsePosition) -> 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.
