Struct ByteOffset

pub struct ByteOffset(pub usize);

A byte offset into the input where an error may have occurred

&str Example

use nom_supreme::final_parser::{ByteOffset, RecreateContext};

let original_input = "Hello,\nWorld!\n";
let tail = &original_input[9..];

assert_eq!(
   ByteOffset::recreate_context(original_input, tail),
   ByteOffset(9),
);

# &[u8] Example

use nom_supreme::final_parser::{ByteOffset, RecreateContext};

let original_input = b"GET / HTTP/1.1\r\n";
let tail = &original_input[6..];

assert_eq!(
   ByteOffset::recreate_context(&original_input[..], tail),
   ByteOffset(6),
);

Trait Implementations

impl Clone for ByteOffset

fn clone(&self) -> ByteOffset

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ByteOffset

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

Formats the value using the given formatter.

impl PartialEq for ByteOffset

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

impl<I: Offset> RecreateContext<I> for ByteOffset

fn recreate_context(original_input: I, tail: I) -> Self

Given the original input, as well as the context reported by nom, recreate a context in the original string where the error occurred.
