Function from_bytes_unchecked
pub unsafe fn from_bytes_unchecked<T, E>(bytes: &[u8]) -> Result<T, E> ⓘ
Available on crate feature
dep_rkyv
only.Expand description
Deserialize a value from the given bytes.
This function does not check that the data is valid. Use from_bytes
to
validate the data instead.
This is part of the low-level API.
§Safety
The byte slice must represent a valid archived type when accessed at the default root position. See the module docs for more information.
§Example
use core::mem::MaybeUninit;
use rkyv::{
access_unchecked,
api::low::{from_bytes_unchecked, to_bytes_in_with_alloc},
rancor::Failure,
ser::{allocator::SubAllocator, writer::Buffer},
util::Align,
with::InlineAsBox,
Archive, Deserialize, Serialize,
};
let mut output = Align([MaybeUninit::<u8>::uninit(); 256]);
let mut alloc = [MaybeUninit::<u8>::uninit(); 256];
#[derive(Archive, Serialize, Deserialize, Debug, PartialEq)]
struct Example {
inner: i32,
}
let value = Example { inner: 42 };
let bytes = to_bytes_in_with_alloc::<_, _, Failure>(
&value,
Buffer::from(&mut *output),
SubAllocator::new(&mut alloc),
)
.unwrap();
let deserialized =
unsafe { from_bytes_unchecked::<Example, Failure>(&*bytes).unwrap() };
assert_eq!(value, deserialized);
