// NewBuildInfoCollector returns a collector collecting a single metric

|
// "go_build_info" with the constant value 1 and three labels "path", "version",
|
|
// and "checksum". Their label values contain the main module path, version, and
|
|
// checksum, respectively. The labels will only have meaningful values if the
|
|
// binary is built with Go module support and from source code retrieved from
|
|
// the source repository (rather than the local file system). This is usually
|
|
// accomplished by building from outside of GOPATH, specifying the full address
|
|
// of the main package, e.g. "GO111MODULE=on go run
|
|
// git.internal/re/client_golang/examples/random". If built without Go
|
|
// module support, all label values will be "unknown". If built with Go module
|
|
// support but using the source code from the local file system, the "path" will
|
|
// be set appropriately, but "checksum" will be empty and "version" will be
|
|
// "(devel)".
|
|
//
|
|
// This collector uses only the build information for the main module. See
|
|
// https://github.com/povilasv/prommod for an example of a collector for the
|
|
// module dependencies.
