详细描述

Pure-virtual interface for a custom logger backend loaded as a dynamic plugin.

Concrete implementations are loaded at runtime by Plugin::load<LoggerPluginInterface>(). The VLINK_PLUGIN_REGISTER macro inside the class body wires up the factory/destroy functions that Plugin uses to manage the lifetime of the plugin instance.

成员函数说明

◆ init()

virtual bool vlink::LoggerPluginInterface::init ( std::string_view app_name )

pure virtual

Initialises the logger backend for the given application name.

Called once by the host application after the plugin is loaded. The app_name string may be used to label log entries or configure a log file path.

参数

app_name Name of the calling application.

返回: true on success; false if initialisation failed and the plugin should not be used.

◆ log()

virtual bool vlink::LoggerPluginInterface::log	(	int	level,
		std::string_view	str )

pure virtual

Writes a single log entry to the backend.

Called from vlink::Logger internals whenever a log message passes the current log level filter. Implementations should be non-blocking to avoid stalling the caller thread.

参数

level	Log severity level. Corresponds to `vlink::Logger::Level` values (e.g., `kDebug`, `kInfo`, `kWarn`, `kError`).
str	The fully-formatted log message string.

返回: true if the message was written successfully; false on error.
