}

A Storage is an append-only structure that can update a header section.

Required Methods

fn initialize<E: Encode>(&mut self, header: &E) -> Result<usize, EncodeError>

This rewinds the storage, serialize the header and jumps to the beginning of the user data storage.

fn post_update_header<E: Encode>( &mut self, header: &E, ) -> Result<usize, EncodeError>

This updates the header leaving the position to the end of the user data storage.

fn append<E: Encode>(&mut self, entry: &E) -> Result<usize, EncodeError>

Appends the entry to the user data storage.

fn flush(&mut self) -> CuResult<usize>

Flushes the section to the underlying storage

Provided Methods

fn is_sealed(&self) -> bool

Whether this handle was sealed by section reclamation.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
