pub struct ZeroSlice<T: AsULE>(/* private fields */);
Expand description
A zero-copy “slice”, i.e. the zero-copy version of [T]
. This behaves
similarly to ZeroVec<T>
, however ZeroVec<T>
is allowed to contain
owned data and as such is ideal for deserialization since most human readable
serialization formats cannot unconditionally deserialize zero-copy.
This type can be used inside VarZeroVec<T>
and ZeroMap
:
This essentially allows for the construction of zero-copy types isomorphic to Vec<Vec<T>>
by instead
using VarZeroVec<ZeroSlice<T>>
. See the VarZeroVec
docs for an example.
§Examples
Const-construct a ZeroSlice of u16:
use zerovec::ule::AsULE;
use zerovec::ZeroSlice;
const DATA: &ZeroSlice<u16> =
ZeroSlice::<u16>::from_ule_slice(&<u16 as AsULE>::ULE::from_array([
211, 281, 421, 32973,
]));
assert_eq!(DATA.get(1), Some(281));

pub fn parse_byte_slice(bytes: &[u8]) -> Result<&Self, ZeroVecError>

pub const unsafe fn from_bytes_unchecked(bytes: &[u8]) -> &Self
Uses a &[u8]
buffer as a ZeroVec<T>
without any verification.
§Safety
bytes
need to be an output from ZeroSlice::as_bytes()
.
sourcepub const fn from_ule_slice(slice: &[T::ULE]) -> &Self
pub const fn from_ule_slice(slice: &[T::ULE]) -> &Self
Construct a &ZeroSlice<T>
from a slice of ULEs.
This function can be used for constructing ZeroVecs in a const context, avoiding parsing checks.

for an example.

pub fn from_boxed_slice(slice: Box<[T::ULE]>) -> Box<Self>

from a boxed slice of ULEs
sourcepub fn as_bytes(&self) -> &[u8]

byte buffer representation.
Useful for serialization.

zerovec.len() * std::mem::size_of::<<u16 as AsULE>::ULE>()
);

let zerovec: ZeroVec<u16> =
ZeroVec::parse_byte_slice(bytes).expect("infallible");
assert!(!zerovec.is_empty());
let emptyvec: ZeroVec<u16> =
ZeroVec::parse_byte_slice(&[]).expect("infallible");
assert!(emptyvec.is_empty());
source§impl<T> ZeroSlice<T>where
T: AsULE,
impl<T> ZeroSlice<T>where
T: AsULE,
sourcepub fn get(&self, index: usize) -> Option<T>
pub fn get(&self, index: usize) -> Option<T>
Gets the element at the specified index. Returns None
if out of range.
§Example
use zerovec::ZeroVec;
let bytes: &[u8] = &[0xD3, 0x00, 0x19, 0x01, 0xA5, 0x01, 0xCD, 0x80];

pub fn get_as_array<const N: usize>(&self) -> Option<[T; N]>
Gets the entire slice as an array of length N
. Returns None
if the slice
does not have exactly N
elements.
§Example
use zerovec::ZeroVec;
let bytes: &[u8] = &[0xD3, 0x00, 0x19, 0x01, 0xA5, 0x01, 0xCD, 0x80];

assert_eq!(array[2], 421);
sourcepub fn get_subslice(&self, range: Range<usize>) -> Option<&ZeroSlice<T>>

.
§Example
use zerovec::ZeroVec;
let bytes: &[u8] = &[0xD3, 0x00, 0x19, 0x01, 0xA5, 0x01, 0xCD, 0x80];
let zerovec: ZeroVec<u16> =

assert_eq!(
zerovec.get_subslice(1..3),
Some(&*ZeroVec::from_slice_or_alloc(&[0x0119, 0x01A5]))
);
assert_eq!(zerovec.get_subslice(3..5), None);
sourcepub fn get_ule_ref(&self, index: usize) -> Option<&T::ULE>
pub fn get_ule_ref(&self, index: usize) -> Option<&T::ULE>
Get a borrowed reference to the underlying ULE type at a specified index.
Prefer Self::get()
over this method where possible since working
directly with ULE
types is less ergonomic
sourcepub const fn cast<P>(&self) -> &ZeroSlice<P>
pub const fn cast<P>(&self) -> &ZeroSlice<P>
Casts a ZeroSlice<T>
to a compatible ZeroSlice<P>
.
T
and P
are compatible if they have the same ULE
representation.
If the ULE
s of T
and P
are different, use Self::try_as_converted()
.
§Examples
use zerovec::ZeroSlice;
const BYTES: &[u8] = &[0xD3, 0x00, 0x19, 0x01, 0xA5, 0x01, 0xCD, 0x80];

pub fn try_as_converted<P: AsULE>(&self) -> Result<&ZeroSlice<P>, ZeroVecError>
Converts a &ZeroSlice<T>
into a &ZeroSlice<P>
.
The resulting slice will have the same length as the original slice
if and only if T::ULE
and P::ULE
are the same size.
If T
and P
have the exact same ULE
, use Self::cast()
.
§Examples
use zerovec::ZeroSlice;
