Info logs a non-error message with the given key/value pairs as context. The level argument is provided for optional logging. This method will only b

Error logs an error, with the given message and key/value pairs as context. See Logger.Error for more details.

New returns a new Logger instance. This is primarily used by libraries implementing LogSink, rather than end users. Passing a nil sink will create a

Discard returns a Logger that discards all messages logged to it. It can be used whenever the caller is not interested in the logs. Logger instances

ToSlogHandler returns a slog.Handler which writes to the same sink as the Logger. The returned logger writes all records with level >= slog.LevelErro

V returns a new Logger instance for a specific verbosity level, relative to this Logger. In other words, V-levels are additive. A higher verbosity l

FromSlogHandler returns a Logger which writes to the slog.Handler. The logr verbosity level is mapped to slog levels such that V(0) becomes slog.Leve

NewFormatter constructs a Formatter which emits a JSON-like key=value format.

NewJSON returns a logr.Logger which is implemented by an arbitrary function and produces JSON output.

WithValues returns a new LogSink with additional key/value pairs. See Logger.WithValues for more details.

NewFormatterJSON constructs a Formatter which emits strict JSON.

WithCallDepth returns a LogSink that will offset the call stack by the specified number of frames when logging call site information. If depth is 0,

WithName returns a new LogSink with the specified name appended. See Logger.WithName for more details.

New returns a logr.Logger which is implemented by an arbitrary function.

slogSink wrapper of slog's JSONHandler, for comparison

Enabled tests whether this LogSink is enabled at the specified V-level. For example, commandline flags might be used to set the logging verbosity and

NewStdoutLogger returns a logr.Logger that prints to stdout.

GetSink returns the stored sink.

Info logs a non-error message with the given key/value pairs as context. The msg argument should be used to add some constant description to the log

setSink stores the sink and updates any related fields. It mutates the logger and thus is only safe to use for loggers that are not currently being us

AddValues adds key-value pairs to the set of saved values to be logged with each log line.

WithCallStackHelper returns a new Logger instance that skips the direct caller when logging call site information, if possible. This is useful for us

RunSlogTests runs slogtest.TestHandler on a given slog.Handler, which is expected to emit JSON into the provided buffer.

sanitize ensures that a list of key-value pairs has a value for every key (adding a value if needed) and that each key is a string (substituting a key

AddCallDepth increases the number of stack-frames to skip when attributing the log line to a file and line.

AddName appends the specified name. funcr uses '/' characters to separate name elements. Callers should not pass '/' in the provided name string, bu

FromContext returns a Logger from ctx or an error if no Logger is found.

GetCallStackHelper returns a function that must be called to mark the direct caller as helper function when logging call site information.

NewWithInterface returns a logr.Logger that prints through a TestingT object. In contrast to the simpler New, output formatting can be configured.

WithValues returns a new Logger instance with additional key/value pairs. See Info for documentation on how key/value pairs work.

render produces a log line, ready to use.

FormatError renders an Error log message into strings. The prefix will be empty when no names were set (via AddNames), or when the output is configur

FormatInfo renders an Info log message into strings. The prefix will be empty when no names were set (via AddNames), or when the output is configured

GetV returns the verbosity level of the logger. If the logger's LogSink is nil as in the Discard logger, this will always return 0.

IsZero returns true if this logger is an uninitialized zero value

NewContext returns a new Context, derived from ctx, which carries the provided Logger.

NewWithOptions returns a logr.Logger that prints through a testing.T object. In contrast to the simpler New, output formatting can be configured.

attrToKVs appends a slog.Attr to a logr-style kvList. It handle slog Groups and other details of slog.

Enabled tests whether this Logger is enabled. For example, commandline flags might be used to set the logging verbosity and disable some info logs.

Error logs an error, with the given message and key/value pairs as context. It functions similarly to Info, but may have unique behavior, and should b

FromContextAsSlogLogger returns a slog.Logger from ctx or nil if no such Logger is found.

FromContextOrDiscard returns a Logger from ctx. If no Logger is found, this returns a Logger that discards all log messages.

GetLevel is used for black box unit testing.

Init receives optional information about the logr library for LogSink implementations that need it.

MarshalLog can be used to: - ensure that structs are not logged as strings when the original value has a String method: return a different type withou

New returns a logr.Logger that prints through a testing.T object. Info logs are only enabled at V(0).

NewContextWithSlogLogger returns a new Context, derived from ctx, which carries the provided slog.Logger.
