Struct ntex_bytes::Bytes

pub struct Bytes { /* fields omitted */ }

A reference counted contiguous slice of memory.

Bytes is an efficient container for storing and operating on contiguous slices of memory. It is intended for use primarily in networking code, but could have applications elsewhere as well.

Bytes values facilitate zero-copy network programming by allowing multiple Bytes objects to point to the same underlying memory. This is managed by using a reference count to track when the memory is no longer needed and can be freed.

use ntex_bytes::Bytes;

let mut mem = Bytes::from(&b"Hello world"[..]);
let a = mem.slice(0..5);

assert_eq!(&a[..], b"Hello");

let b = mem.split_to(6);

assert_eq!(&mem[..], b"world");
assert_eq!(&b[..], b"Hello ");

Memory layout

The Bytes struct itself is fairly small, limited to a pointer to the memory and 4 usize fields used to track information about which segment of the underlying memory the Bytes handle has access to.

The memory layout looks like this:

+-------+
| Bytes |
+-------+
 /      \_____
|              \
v               v
+-----+------------------------------------+
| Arc |         |      Data     |          |
+-----+------------------------------------+

Bytes keeps both a pointer to the shared Arc containing the full memory slice and a pointer to the start of the region visible by the handle. Bytes also tracks the length of its view into the memory.

Sharing

The memory itself is reference counted, and multiple Bytes objects may point to the same region. Each Bytes handle point to different sections within the memory region, and Bytes handle may or may not have overlapping views into the memory.

   Arc ptrs                   +---------+
   ________________________ / | Bytes 2 |
  /                           +---------+
 /          +-----------+     |         |
|_________/ |  Bytes 1  |     |         |
|           +-----------+     |         |
|           |           | ___/ data     | tail
|      data |      tail |/              |
v           v           v               v
+-----+---------------------------------+-----+
| Arc |     |           |               |     |
+-----+---------------------------------+-----+

Mutating

While Bytes handles may potentially represent overlapping views of the underlying memory slice and may not be mutated, BytesMut handles are guaranteed to be the only handle able to view that slice of memory. As such, BytesMut handles are able to mutate the underlying memory. Note that holding a unique view to a region of memory does not mean that there are no other Bytes and BytesMut handles with disjoint views of the underlying memory.

Inline bytes

As an optimization, when the slice referenced by a Bytes or BytesMut handle is small enough ¹, with_capacity will avoid the allocation by inlining the slice directly in the handle. In this case, a clone is no longer “shallow” and the data will be copied. Converting from a Vec will never use inlining.

Implementations

impl Bytes

pub fn with_capacity(capacity: usize) -> Bytes

Creates a new Bytes with the specified capacity.

The returned Bytes will be able to hold at least capacity bytes without reallocating. If capacity is under 4 * size_of::<usize>() - 1, then BytesMut will not allocate.

It is important to note that this function does not specify the length of the returned Bytes, but only the capacity.

Examples

use ntex_bytes::Bytes;

let mut bytes = Bytes::with_capacity(64);

// `bytes` contains no data, even though there is capacity
assert_eq!(bytes.len(), 0);

bytes.extend_from_slice(&b"hello world"[..]);

assert_eq!(&bytes[..], b"hello world");

pub const fn new() -> Bytes

Creates a new empty Bytes.

This will not allocate and the returned Bytes handle will be empty.

Examples

use ntex_bytes::Bytes;

let b = Bytes::new();
assert_eq!(&b[..], b"");

pub const fn from_static(bytes: &'static [u8]) -> Bytes

Creates a new Bytes from a static slice.

The returned Bytes will point directly to the static slice. There is no allocating or copying.

Examples

use ntex_bytes::Bytes;

let b = Bytes::from_static(b"hello");
assert_eq!(&b[..], b"hello");

pub fn len(&self) -> usize

Returns the number of bytes contained in this Bytes.

Examples

use ntex_bytes::Bytes;

let b = Bytes::from(&b"hello"[..]);
assert_eq!(b.len(), 5);

pub fn is_empty(&self) -> bool

Returns true if the Bytes has a length of 0.

Examples

use ntex_bytes::Bytes;

let b = Bytes::new();
assert!(b.is_empty());

pub fn is_inline(&self) -> bool

Return true if the Bytes uses inline allocation

Examples

use ntex_bytes::Bytes;

assert!(Bytes::with_capacity(4).is_inline());
assert!(!Bytes::from(Vec::with_capacity(4)).is_inline());
assert!(!Bytes::with_capacity(1024).is_inline());

pub fn copy_from_slice(data: &[u8]) -> Self

Creates Bytes instance from slice, by copying it.

pub fn slice(&self, range: impl RangeBounds<usize>) -> Bytes

Returns a slice of self for the provided range.

This will increment the reference count for the underlying memory and return a new Bytes handle set to the slice.

This operation is O(1).

Examples

use ntex_bytes::Bytes;

let a = Bytes::from(&b"hello world"[..]);
let b = a.slice(2..5);

assert_eq!(&b[..], b"llo");

Panics

Requires that begin <= end and end <= self.len(), otherwise slicing will panic.

pub fn slice_ref(&self, subset: &[u8]) -> Bytes

Returns a slice of self that is equivalent to the given subset.

When processing a Bytes buffer with other tools, one often gets a &[u8] which is in fact a slice of the Bytes, i.e. a subset of it. This function turns that &[u8] into another Bytes, as if one had called self.slice() with the offsets that correspond to subset.

This operation is O(1).

Examples

use ntex_bytes::Bytes;

let bytes = Bytes::from(&b"012345678"[..]);
let as_slice = bytes.as_ref();
let subset = &as_slice[2..6];
let subslice = bytes.slice_ref(&subset);
assert_eq!(&subslice[..], b"2345");

Panics

Requires that the given sub slice is in fact contained within the Bytes buffer; otherwise this function will panic.

pub fn split_off(&mut self, at: usize) -> Bytes

Splits the bytes into two at the given index.

Afterwards self contains elements [0, at), and the returned Bytes contains elements [at, len).

This is an O(1) operation that just increases the reference count and sets a few indices.

Examples

use ntex_bytes::Bytes;

let mut a = Bytes::from(&b"hello world"[..]);
let b = a.split_off(5);

assert_eq!(&a[..], b"hello");
assert_eq!(&b[..], b" world");

Panics

Panics if at > len.

pub fn split_to(&mut self, at: usize) -> Bytes

Splits the bytes into two at the given index.

Afterwards self contains elements [at, len), and the returned Bytes contains elements [0, at).

This is an O(1) operation that just increases the reference count and sets a few indices.

Examples

use ntex_bytes::Bytes;

let mut a = Bytes::from(&b"hello world"[..]);
let b = a.split_to(5);

assert_eq!(&a[..], b" world");
assert_eq!(&b[..], b"hello");

Panics

Panics if at > len.

pub fn truncate(&mut self, len: usize)

Shortens the buffer, keeping the first len bytes and dropping the rest.

If len is greater than the buffer’s current length, this has no effect.

The split_off method can emulate truncate, but this causes the excess bytes to be returned instead of dropped.

Examples

use ntex_bytes::Bytes;

let mut buf = Bytes::from(&b"hello world"[..]);
buf.truncate(5);
assert_eq!(buf, b"hello"[..]);

pub fn trimdown(&mut self)

Shortens the buffer to len bytes and dropping the rest.

This is useful if underlying buffer is larger than cuurrent bytes object.

Examples

use ntex_bytes::Bytes;

let mut buf = Bytes::from(&b"hello world"[..]);
buf.trimdown();
assert_eq!(buf, b"hello world"[..]);

pub fn clear(&mut self)

Clears the buffer, removing all data.

Examples

use ntex_bytes::Bytes;

let mut buf = Bytes::from(&b"hello world"[..]);
buf.clear();
assert!(buf.is_empty());

pub fn try_mut(self) -> Result<BytesMut, Bytes>

Attempts to convert into a BytesMut handle.

This will only succeed if there are no other outstanding references to the underlying chunk of memory. Bytes handles that contain inlined bytes will always be convertible to BytesMut.

Examples

use ntex_bytes::Bytes;

let a = Bytes::copy_from_slice(&b"Mary had a little lamb, little lamb, little lamb..."[..]);

// Create a shallow clone
let b = a.clone();

// This will fail because `b` shares a reference with `a`
let a = a.try_mut().unwrap_err();

drop(b);

// This will succeed
let mut a = a.try_mut().unwrap();

a[0] = b'b';

assert_eq!(&a[..4], b"bary");

pub fn to_mut(&mut self) -> &mut BytesMut

Acquires a mutable reference to the owned form of the data.

Clones the data if it is not already owned.

pub fn extend_from_slice(&mut self, extend: &[u8])

Appends given bytes to this object.

If this Bytes object has not enough capacity, it is resized first. If it is shared (refcount > 1), it is copied first.

This operation can be less effective than the similar operation on BytesMut, especially on small additions.

Examples

use ntex_bytes::Bytes;

let mut buf = Bytes::from("aabb");
buf.extend_from_slice(b"ccdd");
buf.extend_from_slice(b"eeff");

assert_eq!(b"aabbccddeeff", &buf[..]);

pub fn unsplit(&mut self, other: Bytes)

Combine splitted Bytes objects back as contiguous.

If Bytes objects were not contiguous originally, they will be extended.

Examples

use ntex_bytes::Bytes;

let mut buf = Bytes::with_capacity(64);
buf.extend_from_slice(b"aaabbbcccddd");

let splitted = buf.split_off(6);
assert_eq!(b"aaabbb", &buf[..]);
assert_eq!(b"cccddd", &splitted[..]);

buf.unsplit(splitted);
assert_eq!(b"aaabbbcccddd", &buf[..]);

pub fn iter(&self) -> Iter<'_, u8>

Returns an iterator over the bytes contained by the buffer.

Examples

use ntex_bytes::{Buf, Bytes};

let buf = Bytes::from(&b"abc"[..]);
let mut iter = buf.iter();

assert_eq!(iter.next().map(|b| *b), Some(b'a'));
assert_eq!(iter.next().map(|b| *b), Some(b'b'));
assert_eq!(iter.next().map(|b| *b), Some(b'c'));
assert_eq!(iter.next(), None);
