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: Archive + ?Sized>( &mut self, value: &T, resolver: T::Resolver, ) -> Result<usize, E>

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: ArchiveUnsized + ?Sized>( &mut self, value: &T, to: usize, ) -> Result<usize, E>

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.
