type TagOptions

type TagOptions string

TagOptions is the string following a comma in a struct field's "json" tag, or the empty string. It does not include the leading comma.

func ParseTagOptions

func ParseTagOptions(tag string) (tagName string, opts TagOptions)

ParseTagOptions splits a struct field's json tag into its name and comma-separated options.

func (TagOptions) Contains

func (o TagOptions) Contains(optionName string) bool

Contains reports whether a comma-separated list of options contains a particular substr flag. substr must be surrounded by a string boundary or commas.
