Helper methods for Writer.

Provided Methods

fn pad(&mut self, padding: usize) -> Result<(), E>

Advances the given number of bytes as padding.

fn align(&mut self, align: usize) -> Result<usize, E>

Aligns the position of the serializer to the given alignment.

fn align_for<T>(&mut self) -> Result<usize, E>

Aligns the position of the serializer to be suitable to write the given type.

unsafe fn resolve_aligned<T>( &mut self, value: &T, resolver: <T as Archive>::Resolver, ) -> Result<usize, E>

where T: Archive + ?Sized,

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 serializing value
• The serializer must be aligned for a T::Archived

unsafe fn resolve_unsized_aligned<T>( &mut self, value: &T, to: usize, ) -> Result<usize, E>

where T: ArchiveUnsized + ?Sized,

Resolves the given reference with its resolver and writes the archived reference.

Returns the position of the written archived RelPtr.

Safety

The serializer must be aligned for a RelPtr<T::Archived>.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
