Struct Cursor

pub struct Cursor<T> {
    pub data: T,
    pub offset: usize,
}

Fields

data: T

offset: usize

Implementations

impl<'a, T> Cursor<&'a [T]>

pub fn remaining_slice(&self) -> &'a [T]

Returns remaining slice from the current offset. It doesn’t change the offset.

Examples

use util_cursor::Cursor;

let mut cursor = Cursor::new([1, 2].as_ref());

assert_eq!(cursor.remaining_slice(), &[1, 2]);
cursor.offset = 42;
assert!(cursor.remaining_slice().is_empty());

pub fn read_slice(&mut self, len: usize) -> Option<&'a [T]>

Read slice from the current offset.

Example

use util_cursor::Cursor;
let mut view = Cursor::new([1, 2, 3].as_ref());

assert_eq!(view.read_slice(2), Some([1, 2].as_ref()));
assert_eq!(view.read_slice(3), None);

impl<T> Cursor<T>

pub const fn new(data: T) -> Self

Creates a new Cursor<T>.

Examples

use util_cursor::Cursor;

let cursor = Cursor::new([1, 2].as_ref());
