A SampleValue is a representation of a value for a given sample at a given time.

A LabelName is a key for a LabelSet or Metric. It has a value associated therewith.

A LabelValue is an associated value for a LabelName.

A Metric is similar to a LabelSet, but the key difference is that a Metric is a singleton and refers to one and only one stream of samples.

Secret special type for storing secrets.

Time is the number of milliseconds since the epoch (1970-01-01 00:00 UTC) excluding leap seconds.

Fingerprint provides a hash-capable representation of a Metric. For our purposes, FNV-1A 64-bit is used.

A LabelSet is a collection of LabelName and LabelValue pairs. The LabelSet may be fully-qualified down to the point where it may resolve to a single

Format specifies the HTTP content type of the different wire protocols.

enhancedWriter has all the enhanced write functions needed here. bufio.Writer implements it.

Duration wraps time.Duration. It is used to parse the custom duration format from YAML. This type should not propagate beyond the scope of input/outpu

MetricType represents metric type values.

Alert is a generic representation of an alert in the Prometheus eco-system.

Alert is a list of alerts that can be sorted in chronological order.

Authorization contains HTTP authorization credentials.

BasicAuth contains basic HTTP authentication credentials.

Closer is implemented by Encoders that need to be closed to finalize encoding. (For example, OpenMetrics needs a final `# EOF` line.) Note that all E

Config is a struct containing configurable settings for the logger.

DecodeOptions contains options used by the Decoder and in sample extraction.

Decoder types decode an input stream into metric families.

DialContextFunc defines the signature of the DialContext() function implemented by net.Dialer.

DirectorySetter is a config type that contains file paths that may be relative to the file containing the config.

Encoder types encode metric families into an underlying wire protocol.

FingerprintSet is a set of Fingerprints.

Fingerprints represents a collection of Fingerprint subject to a given natural sorting scheme. It implements sort.Interface.

Format controls a logging output format. Not concurrency-safe.

FormatType is a Go enum representing the overall category for the given Format. As the number of Format permutations increases, doing basic string com

HTTPClientConfig configures an HTTP client.

HTTPClientOption defines an option that can be applied to the HTTP client.

Header represents the configuration for a single HTTP header.

Headers represents the configuration for HTTP headers.

Interval describes an interval between two timestamps.

Config is the configuration for using JWT to fetch tokens, commonly known as "two-legged OAuth 2.0".

LabelNames is a sortable LabelName slice. In implements sort.Interface.

LabelPair pairs a name with a value.

LabelPairs is a sortable slice of LabelPair pointers. It implements sort.Interface.

LabelValues is a sortable LabelValue slice. It implements sort.Interface.

Level controls a logging level, with an info default. It wraps slog.LevelVar with string-based level control. Level is safe to be used concurrently.

LogStyle represents the common logging formats in the Prometheus ecosystem.

Matcher describes a matches the value of a given label.

Matrix is a list of time series.

NewTLSConfigFunc returns tls.Config.

OAuth2 is the oauth2 client configuration.

ParseError signals errors while parsing the simple and flat text-based exchange format.

Router wraps httprouter.Router and adds support for prefixed sub-routers, per-request context injections and instrumentation.

Sample is a sample pair associated with a metric. A single sample must either define Value or Histogram but not both. Histogram == nil implies the Val

SampleDecoder wraps a Decoder to extract samples from the metric families decoded by the wrapped Decoder.

SamplePair pairs a SampleValue with a Timestamp.

SampleStream is a stream of Values belonging to an attached COWMetric.

Samples is a sortable Sample slice. It implements sort.Interface.

Scalar is a scalar value evaluated at the set timestamp.

SecretManager manages secret data mapped to names known as "references" or "refs".

SecretManagerOption is an option for providing a SecretManager.

Silence defines the representation of a silence definition in the Prometheus eco-system.

String is a string value evaluated at the set timestamp.

TLSConfig configures the options for TLS connections.

TLSConfigOption defines an option that can be applied to the HTTP client.

TextParser is used to parse the simple and flat text-based exchange format. TextParser instances must be created with NewTextParser, the zero value o

URL is a custom URL type that allows validation at configuration load time.

ValidationScheme is a Go enum for determining how metric and label names will be validated by this library.

Value is a generic interface for values resulting from a query evaluation.

Vector is basically only an alias for Samples, but the contract is that in a Vector, all Samples have the same timestamp.

errDecoder is an error-state decoder that always returns the same error.

jwtSource is a source that always does a signed JWT request for a token. It should typically be wrapped with a reuseTokenSource.
