Module log_service 

Structured kernel log service

Provides a fixed-size, heap-free circular buffer of structured log entries. Each entry carries a timestamp, severity level, subsystem tag, and a fixed-length message. The service is stored as global state behind a [spin::Mutex] and accessed through a small public API.

Usage

log_service::log_init();
log_service::klog(LogLevel::Info, "sched", "scheduler initialized");
let n = log_service::log_count();

The buffer holds up to [LOG_BUFFER_CAPACITY] entries. Once full it wraps around and silently overwrites the oldest entries.

Structs

LogEntry

A single structured log entry.

Enums

LogLevel

Severity levels for kernel log messages.

Functions

klog

Record a structured log entry.

log_clear

Clear all log entries.

log_count

Return the number of entries currently in the log buffer.

log_drain

Iterate over all buffered log entries from oldest to newest, calling f for each.

log_init

Initialize the kernel log service.
