Functions

func Debug 

func Debug(msg string, args ...any)

Debug prints formatted debug level log message.

func ExtractRequestID added in v0.1.27 

func ExtractRequestID(ctx context.Context) (string, bool)

ExtractRequestID extracts the request id from a context object.

func ExtractSessionID added in v0.1.27 

func ExtractSessionID(ctx context.Context) (string, bool)

ExtractSessionID extracts the session id from a context object.

func Fatal added in v1.0.0 

func Fatal(msg string, args ...any)

Fatal prints formatted error level log message.

func Info 

func Info(msg string, args ...any)

Info prints formatted info level log message.

func JSONLog 

func JSONLog(b bool)

JSONLog turns JSON format on or off.

func Panic 

func Panic(msg string, args ...any)

func SetupGlobal added in v1.0.0 

func SetupGlobal(logger Log)

SetupGlobal overwrites global logger.

func Warning 

func Warning(msg string, args ...any)

func WithNewRequestID added in v0.1.27 

func WithNewRequestID(ctx context.Context, fields ...LoggableField) context.Context

WithNewRequestID does the same thing as WithRequestID but generates a new, random requestId. It can be used when there isn't a single, clear, unique id associated with a request (e.g., a block or tx hash).

func WithNewSessionID added in v0.1.27 

func WithNewSessionID(ctx context.Context, fields ...LoggableField) context.Context

WithNewSessionID does the same thing as WithSessionID but generates a new, random sessionId. It can be used when there isn't a single, clear, unique id associated with a session.

func WithRequestID added in v0.1.27 

func WithRequestID(ctx context.Context, requestID string, fields ...LoggableField) context.Context

WithRequestID returns a context which knows its request ID. A request ID tracks the lifecycle of a single request across all execution contexts, including multiple goroutines, task queues, workers, etc. The canonical example is an incoming message received over the network. Rule of thumb: requests "traverse the heap" and may be passed from one session to another via channels. This requires a requestId string, and optionally, other LoggableFields that are added to context and printed in contextual logs.

func WithSessionID added in v0.1.27 

func WithSessionID(ctx context.Context, sessionID string, fields ...LoggableField) context.Context

WithSessionID returns a context which knows its session ID A session ID tracks a single thread of execution. This may include multiple goroutines running concurrently, but it does not include asynchronous task execution such as task queues handled in separate threads. The canonical example is a single protocol routine, down to the point where an incoming request is either handled, or else handed off to another routine via a channel. Rule of thumb: sessions live entirely on the stack, and never on the heap (and should not be passed over channels). This requires a sessionId string, and optionally, other LoggableFields that are added to context and printed in contextual logs.
