Struct BytesRange

pub struct BytesRange<'a> { /* private fields */ }

Subrange of a StrQueue.

This can be created by StrQueue::bytes_range.

The range can contain any bytes.

Implementations

impl<'a> BytesRange<'a>

Subrange access.

pub fn range<R>(&self, range: R) -> Self

where R: RangeBounds<usize>,

Returns the subrange.

Panics

Panics if the given index is out of range.

impl<'a> BytesRange<'a>

Content length and existence.

pub fn len(&self) -> usize

Returns the total length.

pub fn is_empty(&self) -> bool

Returns true if the range is empty.

impl<'a> BytesRange<'a>

Range and content manipulation.

pub fn clear(&mut self)

Clears the range, removing all elements.

Examples

use str_queue::{PartialHandling, StrQueue};

let queue = StrQueue::from(b"Hello \xce");
let mut range = queue.bytes_range(..);
assert!(!range.is_empty());

range.clear();
assert!(range.is_empty());
// Only the range is cleared. The underlying queue does not change.
assert!(!queue.is_empty());

pub fn pop(&mut self) -> Option<u8>

Pops the first byte in the range and returns it.

Examples

use str_queue::StrQueue;

let queue = StrQueue::from("abc\u{03B1}");
let mut range = queue.bytes_range(..);

assert_eq!(range.pop(), Some(b'a'));
assert_eq!(range.pop(), Some(b'b'));
assert_eq!(range.pop(), Some(b'c'));
assert_eq!(range.pop(), Some(b'\xce'));
assert_eq!(range.pop(), Some(b'\xb1'));
assert_eq!(range.pop(), None);
assert!(range.is_empty());
