type ObjectFile ¶
type ObjectFile struct {
BuildID string
Path string
Size int64
Modtime time.Time
// If exists, will be released when the parent ObjectFile is released.
// Go GC with a finalizer works correctly even with cyclic references.
DebugFile *ObjectFile
// contains filtered or unexported fields
}

type Pool struct {
// contains filtered or unexported fields
}
func NewPool ¶ added in v0.20.0

func (*Pool) NewFile ¶ added in v0.20.0
func (p *Pool) NewFile(f *os.File) (_ *ObjectFile, err error)
NewFile creates a new ObjectFile reference from an existing file. The returned reference should be released after use. The file will be closed when the reference is released.
func (*Pool) Open ¶ added in v0.20.0
