Functions

func ExistsOrError

func ExistsOrError(fpath string, isFileExists FileExistsFunc) error

ExistsOrError checks if the file specified by fpath exists.

It returns an error if the file does not exist.

func ExtensionOrError

func ExtensionOrError(parts *[]string, filename string) error

It expects parts to contain two elements: the filename and its extension. Returns an error if the filename doesn't have a valid extension format.

func SupportedOrError

func SupportedOrError(extension string) error

SupportedOrError checks if the provided extension is among the supported ones.

It compares the extension parameter against a predefined list of valid extensions (jpg, jpeg, png). Returns an error if the extension is not supported.

func ValidateSize

func ValidateSize(size string) error

ValidateSize validates the format of the size string.

It checks if the size string matches the `<width>x<height>` format using a regular expression. Returns an error if the size string is empty, doesn't match the expected format, or if there was an error compiling the regular expression.
