Functions ¶
func Do ¶ added in v0.19.0
func Do(fn []func() error) error
Do executes each function in the slice in order. If any function returns an error, it is returned immediately.
func FindDuplicates ¶ added in v0.7.0
func FindDuplicates(hashes []*Phash, distance int) [][]int
func GetBase64StringFromData ¶
func GetBase64StringFromData(data []byte) string
GetBase64StringFromData returns the given byte slice as a base64 encoded string
func GetDataFromBase64String ¶
func GetDataFromBase64String(encodedString string) ([]byte, error)
GetDataFromBase64String returns the given base64 encoded string as a byte slice
func GetVTTTime ¶
func GetVTTTime(fracSeconds float64) string
GetVTTTime returns a timestamp appropriate for VTT files (hh:mm:ss.mmm)
func GetYMDFromDatabaseDate ¶
func GetYMDFromDatabaseDate(dateString string) string
func IsTrue ¶ added in v0.6.0
func IsTrue(b *bool) bool
IsTrue returns true if the bool pointer is not nil and true.
func NotNilFields ¶ added in v0.11.0
func NotNilFields(subject interface{}, tag string) []string
NotNilFields returns the matching tag values of fields from an object that are not nil. Panics if the provided object is not a struct.
func ParseDateStringAsFormat ¶
func ParseDateStringAsFormat(dateString string, format string) (string, error)
func ParseDateStringAsTime ¶
func ParseDateStringAsTime(dateString string) (time.Time, error)
func PhashToString ¶ added in v0.7.0
func PhashToString(phash int64) string
func ProcessBase64Image ¶
func ProcessBase64Image(imageString string) ([]byte, error)
ProcessBase64Image transforms a base64 encoded string from a form post and returns the image itself as a byte slice.
func ProcessImageInput ¶ added in v0.6.0
func ProcessImageInput(ctx context.Context, imageInput string) ([]byte, error)
ProcessImageInput transforms an image string either from a base64 encoded string, or from a URL, and returns the image as a byte slice
func ReadImageFromURL ¶ added in v0.6.0
func ReadImageFromURL(ctx context.Context, url string) ([]byte, error)
ReadImageFromURL returns image data from a URL
func ServeImage ¶ added in v0.3.0
func ServeImage(image []byte, w http.ResponseWriter, r *http.Request) error
func StrFormat ¶ added in v0.8.0
func StrFormat(format string, m StrFormatMap) string
StrFormat formats the provided format string, replacing placeholders in the form of "{fieldName}" with the values in the provided StrFormatMap.
For example,
StrFormat("{foo} bar {baz}", StrFormatMap{
"foo": "bar",
"baz": "abc",
})
would return: "bar bar abc"
Example ¶
Output: bar bar abc
func StringToPhash ¶ added in v0.8.0
func StringToPhash(s string) (int64, error)
func Timeout ¶ added in v0.7.0
func Timeout(todo func(), waitTime time.Duration, onTimeout func(done chan struct{}))
Timeout executes the provided todo function, and waits for it to return. If the function does not return before the waitTime duration is elapsed, then onTimeout is executed, passing a channel that will be closed when the function returns.
Types ¶
type MutexManager ¶ added in v0.11.0
type MutexManager struct {
// contains filtered or unexported fields
}
MutexManager manages access to mutexes using a mutex type and key.
func NewMutexManager ¶ added in v0.11.0
func NewMutexManager() *MutexManager
NewMutexManager returns a new instance of MutexManager.
type Phash ¶ added in v0.7.0
type Phash struct {
SceneID int `db:"id"`
Hash int64 `db:"phash"`
Neighbors []int
Bucket int
}
type StrFormatMap ¶ added in v0.8.0
type StrFormatMap map[string]interface{}
