Overview

Package schema provides Go types for the OpenAPI 3.1 specification.

Only the subset of the specification needed by this project is implemented: top-level Spec, Info, Server, Paths, PathItem, Operation, RequestBody and MediaType.

Reference: https://spec.openapis.org/oas/v3.1.1

Types

type Components added in v1.6.19 

type Components struct {
	SecuritySchemes map[string]SecurityScheme `json:"securitySchemes,omitempty" yaml:"securitySchemes,omitempty"`

func (MediaType) MarshalYAML added in v1.6.14 

func (m MediaType) MarshalYAML() (any, error)

MarshalYAML serialises MediaType via its JSON form so that the nested *jsonschema.Schema is rendered compactly (only non-zero fields, using JSON omitempty tags that the third-party type provides).

func (*Spec) AddTagGroup added in v1.6.19 

func (s *Spec) AddTagGroup(name string, tags ...string)

AddTagGroup appends a TagGroup that groups the given tags under a sidebar heading in Redoc. If a group with the same name already exists, its tags are replaced.

func (s *Spec) SetServers(servers []Server)

SetServers replaces the servers list in the spec.

func (*Spec) SetSummary added in v1.6.14 

func (s *Spec) SetSummary(summary string)

SetSummary sets the summary field of the spec's Info object.

type Tag struct {
	Name        string `json:"name"                 yaml:"name"` // Required.
	Description string `json:"description,omitzero" yaml:"description,omitempty"`
}

Tag adds metadata to a group of operations identified by the same tag name.

type TagGroup added in v1.6.19 

type TagGroup struct {
	Name string   `json:"name"             yaml:"name"` // The heading displayed in the sidebar.
	Tags []string `json:"tags"             yaml:"tags"` // Tag names belonging to this group.
}
