Types ¶

type Tag ¶

type Tag struct {
	Name   string
	Values Values
}

Tag defines generic tag

func NewTag ¶

func NewTag(name string, value interface{}) *Tag

NewTag creates a tag for supplied tag type

func (*Tag) Append ¶

func (e *Tag) Append(value string)

Append appends tag value element

func NewTags ¶

func NewTags(tagLiteral string) Tags

NewTags create a tags for supplied tag literal

func Parse ¶ added in v0.4.0

func Parse(tagLiteral string) (Tags, error)

Parse parses an entire Go struct-tag literal. Unlike NewTags it rejects a malformed suffix and returns no usable prefix when parsing fails. Repeated tag names are retained; their semantics belong to the consuming owner.

func (*Tags) Append ¶

func (t *Tags) Append(tag string, value string)

Append appends tag values to existing tag or create a new tag

func (Tags) Index ¶

func (t Tags) Index(name string) int

Index returns matched by name tag index

func (Tags) Literal ¶ added in v0.4.0

func (t Tags) Literal() string

Literal renders a complete Go struct-tag literal, retaining explicitly empty values. Stringify keeps its historical omission behavior for existing users.

func (Tags) Lookup ¶

func (t Tags) Lookup(name string) *Tag

Lookup returns matched by name tag

func (*Tags) Set ¶

func (t *Tags) Set(tag string, value string)

Set sets tag value, if tag exists, overrides it

func (*Tags) SetIfNotFound ¶

func (t *Tags) SetIfNotFound(tag string, value string)

func (*Tags) SetTag ¶

func (t *Tags) SetTag(aTag *Tag)

SetTag sets tags, if tag exists, overrides it

func (Tags) Stringify ¶

func (t Tags) Stringify() string

Stringify returns stringified tags representations

type Values ¶

type Values string

Values represents tag values

func (Values) Match ¶

func (v Values) Match(onMatch func(value string) error) error

Match matches elements separated by ,

func (Values) MatchPairs ¶

func (v Values) MatchPairs(onMatch func(key, value string) error) error

MatchPairs matches pairs separated by commas, decoding Go-quoted values.

func (Values) MatchRawPairs ¶ added in v0.4.0

func (v Values) MatchRawPairs(onMatch func(key, value string) error) error

MatchRawPairs uses the same pair tokenizer as MatchPairs but preserves value delimiters. Callers can retain SQL identifier quoting without reparsing tags.

func (Values) Name ¶

func (v Values) Name() (string, Values)

Name returns tag value and remaining values
