chunk()

void agents::Logger::chunk ( const std::string & text )

inlinestatic

Write a raw chunk of text to stdout without any log prefix or newline. Flushes immediately — intended for streaming token output. Respects the current log level: suppressed when level > INFO.

Parameters

text	The text chunk to write

critical()

template<typename... Args>

void agents::Logger::critical ( fmt::format_string< Args... > fmt, Args &&... args )

inlinestatic

Log a message at critical level.

Parameters

fmt	The format string
args	The arguments

debug()

template<typename... Args>

void agents::Logger::debug ( fmt::format_string< Args... > fmt, Args &&... args )

inlinestatic

Log a message at debug level.

Parameters

fmt	The format string
args	The arguments

Examples

prompt_chain_example.cpp, and routing_example.cpp.

error()

template<typename... Args>

void agents::Logger::error ( fmt::format_string< Args... > fmt, Args &&... args )

inlinestatic

Log a message at error level.

Parameters
