Package stacktrace provides support for gathering stack traces efficiently.

ContextWithLogger returns a new `context.Context` that holds a reference to `logger`'s LoggerContext.

For returns a context-aware Logger.

LoggerFromContext returns the `logger` previously associated with `ctx`, or `nil` if no such `logger` could be found.

LoggerOrEmptyFromContext returns the `logger` previously associated with `ctx`, or `Empty` if no such `logger` could be found.

DebugLevel logs are typically voluminous, and are usually disabled in production.

DPanicLevel logs are particularly important errors.

ErrorLevel logs are high-priority.

FatalLevel logs a message, then calls os.Exit(1).

InfoLevel is the default logging priority.

PanicLevel logs a message, then panics.

WarnLevel logs are more important than Info, but don't need individual human review.

Any adds an any-valued key:value pair to a Span.LogFields() record.

Binary constructs a field that carries an opaque binary blob.

Bool adds a bool-valued key:value pair to a Span.LogFields() record.

ByteString constructs a field that carries UTF-8 encoded text as a []byte.

Duration constructs a field with the given key and value.

Error adds an error with the key "error" to a Span.LogFields() record.

Float32 adds a float32-valued key:value pair to a Span.LogFields() record.

Float64 adds a float64-valued key:value pair to a Span.LogFields() record.

Int adds an int-valued key:value pair to a Span.LogFields() record.

Int64 adds an int64-valued key:value pair to a Span.LogFields() record.

NamedError constructs a field that lazily stores err.Error() under the provided key.

Noop creates a no-op log field that should be ignored by the tracer.

Object adds an object-valued key:value pair to a Span.LogFields() record.

Stack constructs a field that stores a stacktrace of the current goroutine under provided key.
