Functions ¶
func ByteToStringUnsafe ¶
func CollapseErrors ¶
CollapseErrors combines errors and writes repeats of each.
func DeduplicateErrors ¶
DeduplicateErrors deduplicates errors.
func DurationToUnit ¶
DurationToUnit converts duration to unit and returns as float64.
func EnsureSliceSize ¶
func Float64ToPrec ¶
Float64ToPrec formats float64 by removing numberics after prec digit.
func IdxShuffle ¶
func IsCancelled ¶
IsCancelled is a faster way to check if the context has been canceled, compared to ctx.Err() != nil
func MsTsToESFormat ¶
MsTsToESFormat converts timestamp in milliseconds to ES time format string.
func MustCreateDir ¶ added in v0.70.0
func MustCreateDir(dirPath string)
MustCreateDir creates directory at dirPath. Handles the case when directory already exists.
func MustFsyncFile ¶ added in v0.70.0
func MustFsyncFile(fpath string)
func MustRemoveFileByPath ¶ added in v0.60.0
func MustRemoveFileByPath(fpath string)
func MustSyncPath ¶
func MustSyncPath(dirPath string)
func MustWriteFileAtomic ¶ added in v0.70.0
func NsTsToESFormat ¶ added in v0.64.0
NsTsToESFormat converts timestamp in nanoseconds to ES time format string. Nanosecond part will not be printed.
func Recover ¶
func Recover(metric prometheus.Counter, err error)
func RecoverToError ¶
func RecoverToError(panicData any, metric prometheus.Counter) error
func RemoveFile ¶ added in v0.62.3
func RemoveFile(file string)
RemoveFile safely removes a file with logging Handles cases where the file already doesn't exist
func SizeToUnit ¶
SizeToUnit converts size in bytes to unit and returns as float64.
func StringToByteUnsafe ¶
func VisitFilesWithExt ¶ added in v0.70.0
VisitFilesWithExt traverses all the files with `ext` extension in `des` directory and calls a `cb` func for each of files.
func WriteFileAtomic ¶ added in v0.70.0
atomicWrite safely writes data to file using atomic replacement pattern
func ZapDurationWithPrec ¶
ZapDurationWithPrec converts duration to unit and forms float64 zap.Field with removed numerics after prec digit.
func ZapFloat64WithPrec ¶
ZapFloat64WithPrec forms float64 zap.Field with removed numerics after prec digit.
func ZapMsTsAsESTimeStr ¶
ZapMsTsAsESTimeStr converts timestamp in milliseconds to ES time format string and forms string zap.Field.
Types ¶
type Bitmask ¶
type Bitmask struct {
// contains filtered or unexported fields
}
func LoadBitmask ¶
func NewBitmask ¶
func (*Bitmask) GetBitmaskBinary ¶
type BufferPool ¶ added in v0.59.0
type BufferPool struct {
// contains filtered or unexported fields
}
func (*BufferPool) Get ¶ added in v0.59.0
func (q *BufferPool) Get() *bytespool.Buffer
func (*BufferPool) Put ¶ added in v0.59.0
func (q *BufferPool) Put(b *bytespool.Buffer)
type MinHeap ¶ added in v0.73.0
MinHeap is a min‑heap for any comparable type. Maintains both a heap structure and a map for fast lookup of items.
func NewMinHeap ¶ added in v0.73.0
NewMinHeap creates and initializes a new MinHeap instance.
func (*MinHeap[T]) Min ¶ added in v0.73.0
Min returns the minimum value in the heap without removing it. Returns (zero value, false) if the heap is empty.
func (*MinHeap[T]) PopMin ¶ added in v0.73.0
PopMin removes and returns the minimum value from the heap. Returns (zero value, false) if the heap is empty.
type ReallocSolver ¶
type ReallocSolver struct {
// contains filtered or unexported fields
}
func NewReallocSolver ¶
func NewReallocSolver(opts ...ReallocSolverOpts) ReallocSolver
func (*ReallocSolver) ReallocParams ¶
func (s *ReallocSolver) ReallocParams(curLen, curCap int) (int, bool)
type ReallocSolverOpts ¶
type ReallocSolverOpts func(*ReallocSolver)
func ReallocSolverLabel ¶
func ReallocSolverLabel(label string) ReallocSolverOpts
