Overview

Package structtag parses the value of a single struct tag into its name and options. It targets the near-universal `name,opt1,opt2` encoding used by encoding/json, gopkg.in/yaml.v3 and most reflection-based decoders, so it is not tied to any one tag key.

Types

type Options 

type Options map[string]struct{}

Options is the set of comma-separated options that follow the name in a struct tag value (for example "omitempty" or "inline").

func Parse 

func Parse(tag string) (string, Options)

Parse splits a struct tag value of the form "name,opt1,opt2" into the name and the set of options. An empty name means the tag carried no explicit name (for example ",inline" or the empty tag), leaving it to the caller to fall back to the field name.

func (Options) Has 

func (o Options) Has(opt string) bool

Has reports whether opt is present in the set.
