pub struct EMMCSectionStorage<BD: BlockDevice> { /* private fields */ }

Trait Implementations

impl<BD: BlockDevice + Send> SectionStorage for EMMCSectionStorage<BD>

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

impl<BD> UnifiedLogWrite<EMMCSectionStorage<BD>> for EMMCLogger<BD>

where BD: BlockDevice + Send + Sync + 'static,

fn add_section( &mut self, entry_type: UnifiedLogType, requested_section_size: usize, ) -> CuResult<SectionHandle<EMMCSectionStorage<BD>>>

A section is a contiguous chunk of memory that can be used to write data. It can store various types of data as specified by the entry_type. The requested_section_size is the size of the section to allocate. It returns a handle to the section that can be used to write data until it is flushed with flush_section, it is then considered unmutable.

fn flush_section(&mut self, section: &mut SectionHandle<EMMCSectionStorage<BD>>)

Flush the given section to the underlying storage.

fn status(&self) -> UnifiedLogStatus

Returns the current status of the unified logger.
