Overview

Package runtimex contains runtime extensions. This package is inspired to https://pkg.go.dev/github.com/m-lab/go/rtx, except that it's simpler.

Variables

var BuildInfo = &BuildInfoRecord{}

BuildInfo is the singleton containing build-time information.

Functions

func Assert

func Assert(assertion bool, message string)

Assert calls panic if assertion is false. The type passed to panic is an error constructed using errors.New(message).

func PanicIfNil

func PanicIfNil(v any, message string)

PanicIfNil calls panic if the given interface is nil. The type passed to panic is an error constructed using errors.New(message).

func PanicIfTrue

func PanicIfTrue(assertion bool, message string)

PanicIfTrue calls panic if assertion is true. The type passed to panic is an error constructed using errors.New(message).

func PanicOnError

func PanicOnError(err error, message string)

PanicOnError calls panic() if err is not nil. The type passed to panic is an error type wrapping the original error.

func Try0

func Try0(err error)

Try0 calls runtimex.PanicOnError if err is not nil.

func Try1

func Try1[T1 any](v1 T1, err error) T1

Try1 is like Try0 but supports functions returning one values and an error.

func Try2

func Try2[T1, T2 any](v1 T1, v2 T2, err error) (T1, T2)

Try2 is like Try1 but supports functions returning two values and an error.

func Try3

func Try3[T1, T2, T3 any](v1 T1, v2 T2, v3 T3, err error) (T1, T2, T3)

Try3 is like Try2 but supports functions returning three values and an error.

Types

type BuildInfoRecord

type BuildInfoRecord struct {
	// GoVersion is the version of go with which this code
	// was compiled or an empty string.
	GoVersion string

	// VcsModified indicates whether the tree was dirty.
	VcsModified string

	// VcsRevision is the VCS revision we compiled.
	VcsRevision string

	// VcsTime is the time of the revision we're building.
	VcsTime string

	// VcsTool is the VCS tool being used.
	VcsTool string
}

BuildInfoRecord contains build-time information.
