Functions

func LimitReader

func LimitReader(r io.Reader, n int64) (limited io.Reader, err error)

LimitReader wraps Reader to make it's Reader stop with ErrLimitReached after n bytes read.

func Min

func Min[T constraints.Integer | ~string](x, y T) (res T)

Min returns the smaller of x or y.

func RegisterGeoUpdater

func RegisterGeoUpdater(onSuccess func())

func UpdateCore

func UpdateCore(execPath string) (err error)

Update performs the auto-updater. It returns an error if the updater failed. If firstRun is true, it assumes the configuration file doesn't exist.

func UpdateGeoDatabases

func UpdateGeoDatabases() error

func UpdateUI

func UpdateUI() error

Types

type LimitReachedError

type LimitReachedError struct {
	Limit int64
}

LimitReachedError records the limit and the operation that caused it.

func (*LimitReachedError) Error

func (lre *LimitReachedError) Error() string

Error implements the [error] interface for *LimitReachedError.

TODO(a.garipov): Think about error string format.
