Logger#

class EdgeLLMLogger : public nvinfer1::ILogger#

Enhanced Logger with automatic location tracking and nvinfer1 compatibility.

Features:

  • Automatic source location tracking (file:line:function)

  • Configurable formatting (timestamps, location info)

  • nvinfer1::ILogger interface for TensorRT integration

  • Multiple log levels with performance optimizations

Parameters:

show – true to show function names, false to hide

Public Static Functions

static inline EdgeLLMLogger &instance() noexcept#

Access the process-wide logger singleton.

The instance is intentionally never destroyed (immortal singleton). TensorRT retains a reference to this ILogger inside its global plugin registry, which is a process-lifetime singleton. If the logger were destroyed at static-destruction time (as a normal global object is), the registry could still emit through it from another thread during runtime teardown or plugin-creator lookup, causing a use-after-free. Never destructing the logger removes that race. The single fixed allocation is reclaimed by the OS at process exit; the pointer stays reachable, so it is not a growing leak.

The function-local static also makes construction thread-safe and immune to the static initialization order fiasco (constructed on first use).

Returns:

Reference to the singleton logger

class ScopedFunctionTracer#

RAII-based function tracer for automatic entry/exit logging.

Creates automatic log messages when entering and exiting a scope. Useful for tracing function execution flow.

Public Functions

inline ScopedFunctionTracer(
EdgeLLMLogger &logger,
char const *funcName,
SourceLocation const &loc,
)#

Constructor that logs function entry.

Parameters:

  • logger – Logger instance to use

  • funcName – Name of the function being traced

  • loc – Source location information

inline ~ScopedFunctionTracer() noexcept#

Destructor that logs function exit.

struct SourceLocation#

Source code location information for automatic tracking.

Captures file, function, and line number information for logging.

Public Functions

inline SourceLocation(
char const *f,
char const *func,
int32_t l,
) noexcept#

Constructor with manual location capture.

Parameters:

  • f – Source file path

  • func – Function name

  • l – Line number

Public Members

char const *file#

Source file path.

char const *function#

Function name.

int32_t lineNumber#

Line number.
