Expand description
A byte sink that knows where it is.
A type that is io::Write
can be wrapped in a
WriteSerializer
to equip it with Serializer
.
It’s important that the memory for archived objects is properly aligned before attempting to
read objects out of it; use an AlignedVec
or the
AlignedBytes
wrappers if they are appropriate.
Required methods
Provided methods
Advances the given number of bytes as padding.
Aligns the position of the serializer to the given alignment.
Aligns the position of the serializer to be suitable to write the given type.
Resolves the given value with its resolver and writes the archived type.
Returns the position of the written archived type.
Safety
resolver
must be the result of serializingvalue
- The serializer must be aligned for a
T::Archived
Archives the given object and returns the position it was archived at.
unsafe fn resolve_unsized_aligned<T: ArchiveUnsized + ?Sized>(
&mut self,
value: &T,
to: usize,
metadata_resolver: T::MetadataResolver
) -> Result<usize, Self::Error>
unsafe fn resolve_unsized_aligned<T: ArchiveUnsized + ?Sized>(
&mut self,
value: &T,
to: usize,
metadata_resolver: T::MetadataResolver
) -> Result<usize, Self::Error>
Resolves the given reference with its resolver and writes the archived reference.
Returns the position of the written archived RelPtr
.
Safety
metadata_resolver
must be the result of serializing the metadata ofvalue
to
must be the position of the serializedvalue
within the archive- The serializer must be aligned for a
RelPtr<T::Archived>
fn serialize_unsized_value<T: SerializeUnsized<Self> + ?Sized>(
&mut self,
value: &T
) -> Result<usize, Self::Error>
fn serialize_unsized_value<T: SerializeUnsized<Self> + ?Sized>(
&mut self,
value: &T
) -> Result<usize, Self::Error>
Archives a reference to the given object and returns the position it was archived at.
