Modules

memmap

Mapped-file adapter for the byte-addressed section chain.

noop

Structs

ApplicationMetadata

Static application identity and configuration, retained outside the data ring.

EndOfLogMarker

Payload stored in the end-of-log section to signal whether the log was cleanly closed.

LogStream

A wrapper around the unifiedlogger that implements the Write trait.

MainHeader

Header of the byte-addressed log. All offsets are relative to the log origin.

SectionContext

Construction identity shared by every section of an application instance.

SectionHandle

A SectionHandle is a handle to a section in the datalogger. It allows tracking the lifecycle of the section.

SectionHeader

One linked section. The allocation includes its 512-byte header reservation.

UnifiedLogStatus

Basic statistics for the unified logger. Note: the total_allocated_space might grow for the std implementation

Enums

AllocatedSection

CapacityPolicy

Behavior when a section needs additional storage.

Constants

MAIN_MAGIC

ID to spot the beginning of a Copper Log

SECTION_HEADER_COMPACT_SIZE

SECTION_MAGIC

ID to spot a section of Copper Log

UNIFIED_LOG_FORMAT_VERSION

Version of the unified log encapsulation only: file headers, section headers, and the layout used to locate sections in a slab.

Traits

SectionStorage

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

UnifiedLogRead

Read back a unified log linearly.

UnifiedLogWrite

The writing interface to the unified logger. Writing is “almost” linear as various streams can allocate sections and track them until they drop them.

Functions

stream_write

Create a new stream to write to the unifiedlogger.
