Struct Slice

pub struct Slice<T> { /* private fields */ }

An owned view into a contiguous sequence of bytes. Slice implements IoBuf.

Implementations

impl<T: IoBuf> Slice<T>

pub fn new(buf: T, begin: usize, end: usize) -> Self

Create a Slice from a buffer and range.

impl<T> Slice<T>

pub const unsafe fn new_unchecked(buf: T, begin: usize, end: usize) -> Self

Create a Slice from a buffer and range without boundary checking.

Safety

begin and end must be within the buffer initialized range.

pub const fn begin(&self) -> usize

Offset in the underlying buffer at which this slice starts.

pub const fn end(&self) -> usize

Ofset in the underlying buffer at which this slice ends.

pub const fn get_ref(&self) -> &T

Gets a reference to the underlying buffer.

pub fn get_mut(&mut self) -> &mut T

Gets a mutable reference to the underlying buffer.

pub fn into_inner(self) -> T

Unwraps this Slice, returning the underlying buffer.

Trait Implementations

impl<T: IoBuf> IoBuf for Slice<T>

fn read_ptr(&self) -> *const u8

Returns a raw pointer to the vector’s buffer.

fn bytes_init(&self) -> usize

Number of initialized bytes.

fn as_slice(&self) -> &[u8]

Returns a slice of the buffer.

fn slice(self, range: impl RangeBounds<usize>) -> Slice<Self>

where Self: Sized,

Returns a view of the buffer with the specified range.

unsafe fn slice_unchecked(self, range: impl RangeBounds<usize>) -> Slice<Self>

where Self: Sized,

Returns a view of the buffer with the specified range without boundary checking.
