Types ¶
type Field ¶
type Field struct {
// contains filtered or unexported fields
}
Field log filed
func Any ¶
Any takes a key and an arbitrary value and chooses the best way to represent them as a field, falling back to a reflection-based approach only if necessary.
Since byte/uint8 and rune/int32 are aliases, Any can't differentiate between them. To minimize surprises, []byte values are treated as binary blobs, byte values are treated as uint8, and runes are always treated as integers.
func Boolp ¶
Boolp constructs a field that carries a *bool. The returned Field will safely and explicitly represent `nil` when appropriate.
func ByteString ¶
ByteString constructs a field that carries UTF-8 encoded text as a []byte. To log opaque binary blobs (which aren't necessarily valid UTF-8), use Binary.
func Complex128 ¶
func Complex128(key string, val complex128) Field
Complex128 constructs a field that carries a complex number. Unlike most numeric fields, this costs an allocation (to convert the complex128 to interface{}).
func Complex128p ¶
func Complex128p(key string, val *complex128) Field
Complex128p constructs a field that carries a *complex128. The returned Field will safely and explicitly represent `nil` when appropriate.
func Complex64 ¶
Complex64 constructs a field that carries a complex number. Unlike most numeric fields, this costs an allocation (to convert the complex64 to interface{}).
func Complex64p ¶
Complex64p constructs a field that carries a *complex64. The returned Field will safely and explicitly represent `nil` when appropriate.
func Duration ¶
Duration constructs a field with the given key and value. The encoder controls how the duration is serialized.
func Durationp ¶
Durationp constructs a field that carries a *time.Duration. The returned Field will safely and explicitly represent `nil` when appropriate.
func Float32 ¶
Float32 constructs a field that carries a float32. The way the floating-point value is represented is encoder-dependent, so marshaling is necessarily lazy.
func Float32p ¶
Float32p constructs a field that carries a *float32. The returned Field will safely and explicitly represent `nil` when appropriate.
func Float64 ¶
Float64 constructs a field that carries a float64. The way the floating-point value is represented is encoder-dependent, so marshaling is necessarily lazy.
func Float64p ¶
Float64p constructs a field that carries a *float64. The returned Field will safely and explicitly represent `nil` when appropriate.
func Int16p ¶
Int16p constructs a field that carries a *int16. The returned Field will safely and explicitly represent `nil` when appropriate.
func Int32p ¶
Int32p constructs a field that carries a *int32. The returned Field will safely and explicitly represent `nil` when appropriate.
func Int64p ¶
Int64p constructs a field that carries a *int64. The returned Field will safely and explicitly represent `nil` when appropriate.
func Int8p ¶
Int8p constructs a field that carries a *int8. The returned Field will safely and explicitly represent `nil` when appropriate.
func Intp ¶
Intp constructs a field that carries a *int. The returned Field will safely and explicitly represent `nil` when appropriate.
func Namespace ¶
Namespace creates a named, isolated scope within the logger's context. All subsequent fields will be added to the new namespace.
This helps prevent key collisions when injecting loggers into sub-components or third-party libraries.
func Object ¶
func Object(key string, val zapcore.ObjectMarshaler) Field
Object constructs a field with the given key and ObjectMarshaler. It provides a flexible, but still type-safe and efficient, way to add map- or struct-like user-defined types to the logging context. The struct's MarshalLogObject method is called lazily.
func Reflect ¶
Reflect constructs a field with the given key and an arbitrary object. It uses an encoding-appropriate, reflection-based function to lazily serialize nearly any object into the logging context, but it's relatively slow and allocation-heavy. Outside tests, Any is always a better choice.
If encoding fails (e.g., trying to serialize a map[int]string to JSON), Reflect includes the error message in the final log output.
func Stack ¶
Stack constructs a field that stores a stacktrace of the current goroutine under provided key. Keep in mind that taking a stacktrace is eager and expensive (relatively speaking); this function both makes an allocation and takes about two microseconds.
func StackSkip ¶
StackSkip constructs a field similarly to Stack, but also skips the given number of frames from the top of the stacktrace.
func Stringer ¶
Stringer constructs a field with the given key and the output of the value's String method. The Stringer's String method is called lazily.
func Stringp ¶
Stringp constructs a field that carries a *string. The returned Field will safely and explicitly represent `nil` when appropriate.
func Time ¶
Time constructs a Field with the given key and value. The encoder controls how the time is serialized.
func Timep ¶
Timep constructs a field that carries a *time.Time. The returned Field will safely and explicitly represent `nil` when appropriate.
func Uint16p ¶
Uint16p constructs a field that carries a *uint16. The returned Field will safely and explicitly represent `nil` when appropriate.
func Uint32p ¶
Uint32p constructs a field that carries a *uint32. The returned Field will safely and explicitly represent `nil` when appropriate.
func Uint64p ¶
Uint64p constructs a field that carries a *uint64. The returned Field will safely and explicitly represent `nil` when appropriate.
func Uint8p ¶
Uint8p constructs a field that carries a *uint8. The returned Field will safely and explicitly represent `nil` when appropriate.
func Uintp ¶
Uintp constructs a field that carries a *uint. The returned Field will safely and explicitly represent `nil` when appropriate.
type Logger ¶
type Logger interface {
WithModule(module string) Logger
Debug(msg string, fields ...Field)
Info(msg string, fields ...Field)
Error(msg string, fields ...Field)
Fatal(msg string, fields ...Field)
Write(p []byte) (n int, err error)
