Module log 

Runtime logging — errlog severity surface plus the rt_* macros.

C parity: modules/libcom/src/error/errlog.{c,h}.

The four rt_* macros route through the tracing facade (the crate’s de-facto logging path) instead of bare eprintln!, so an application’s tracing subscriber controls level filtering, formatting, and sinks uniformly.

The errlog-severity API mirrors errlogSevEnum, errlogSevEnumString, errlogSetSevToLog/errlogGetSevToLog, and errlogSevPrintf — a record’s error messages can be suppressed below a configurable severity threshold, exactly as a C IOC does.

Enums

ErrlogSevEnum

Error-message severity — C errlogSevEnum (errlog.h:49-53).

Functions

erl_warning

C ERL_WARNING (errlog.h:299) — the word an errlog warning line carries, magenta on a terminal console and plain everywhere else.

errlog_get_sev_to_log

Get the current severity-to-log threshold — C errlogGetSevToLog (errlog.c:407-415).

errlog_printf

Emit a pre-formatted message through the errlog facility unconditionally — C errlogVprintf/errlogPrintf (errlog.c:333-364), the no-severity variant.

errlog_set_sev_to_log

Set the severity-to-log threshold — C errlogSetSevToLog (errlog.c:399-405). Messages with a severity below this value are suppressed.

errlog_sev_enum_string

String representation of an errlog severity.

errlog_sev_printf

Emit a pre-formatted error message at the given severity, suppressed when severity is below the errlog_get_sev_to_log threshold.

install_console_subscriber

Make this process’s diagnostics reach the console, if nothing else has.

install_panic_hook

Route panics through errlog, in addition to whatever std already does.

single_line

Render record so it cannot end or split a line in a line-oriented log.
