Types ¶
type BadRequestError ¶
type BadRequestError struct {
Account string
RegistryName string
View string
Operation string
Request string
Cause string
}
func (*BadRequestError) Error ¶
func (e *BadRequestError) Error() string
func (*BadRequestError) Is ¶
func (e *BadRequestError) Is(err error) bool
type DataBag ¶
type DataBag interface {
Get(path string) (interface{}, error)
Set(path string, value interface{}) error
Unset(path string) error
Data() ([]byte, error)
}
DataBag controls access to the registry data storage.
type JSONDataBag ¶
type JSONDataBag map[string]json.RawMessage
JSONDataBag is a simple DataBag implementation that keeps JSON in-memory.
func NewJSONDataBag ¶
func NewJSONDataBag() JSONDataBag
NewJSONDataBag returns a DataBag implementation that stores data in JSON. The top-level of the JSON structure is always a map.
func (JSONDataBag) Copy ¶
func (s JSONDataBag) Copy() JSONDataBag
Copy returns a copy of the databag.
func (JSONDataBag) Data ¶
func (s JSONDataBag) Data() ([]byte, error)
Data returns all of the bag's data encoded in JSON.
func (JSONDataBag) Get ¶
func (s JSONDataBag) Get(path string) (interface{}, error)
Get takes a path and a pointer to a variable into which the value referenced by the path is written. The path can be dotted. For each dot a JSON object is expected to exist (e.g., "a.b" is mapped to {"a": {"b": <value>}}).
func (JSONDataBag) Set ¶
func (s JSONDataBag) Set(path string, value interface{}) error
Set takes a path to which the value will be written. The path can be dotted, in which case, a nested JSON object is created for each sub-key found after a dot. If the value is nil, the entry is deleted.
func (JSONDataBag) Unset ¶
func (s JSONDataBag) Unset(path string) error
type JSONSchema ¶
type JSONSchema struct{}
JSONSchema is the Schema implementation corresponding to JSONDataBag and it's able to validate its data.
func NewJSONSchema ¶
func NewJSONSchema() JSONSchema
NewJSONSchema returns a Schema able to validate a JSONDataBag's data.
func (JSONSchema) SchemaAt ¶
func (v JSONSchema) SchemaAt(path []string) ([]Schema, error)
SchemaAt always returns the JSONSchema.
func (JSONSchema) Type ¶
func (v JSONSchema) Type() SchemaType
func (JSONSchema) Validate ¶
func (s JSONSchema) Validate(jsonData []byte) error
Validate validates that the specified data can be encoded into JSON.
type NotFoundError ¶
type NotFoundError struct {
Account string
RegistryName string
View string
Operation string
Requests []string
Cause string
}
func (*NotFoundError) Error ¶
func (e *NotFoundError) Error() string
func (*NotFoundError) Is ¶
func (e *NotFoundError) Is(err error) bool
type Registry ¶
type Registry struct {
Account string
Name string
Schema Schema
// contains filtered or unexported fields
}
Registry holds a series of related views.
func New ¶
func New(account string, registryName string, views map[string]interface{}, schema Schema) (*Registry, error)
New returns a new registry with the specified views and their rules.
func (*Registry) GetViewsAffectedByPath ¶
GetViewsAffectedByPath returns all the views in the registry that have visibility into a storage path.
type Schema ¶
type Schema interface {
Validate(data []byte) error
// SchemaAt returns the schemas (e.g., string, int, etc) that may be at the
// provided path. If the path cannot be followed, an error is returned.
SchemaAt(path []string) ([]Schema, error)
// Type returns the SchemaType corresponding to the Schema.
Type() SchemaType
}
Schema takes in data from the DataBag and validates that it's valid and could be committed.
type SchemaType ¶
type SchemaType uint
const ( Int SchemaType = iota Number String Bool Map Array Any Alt )
func (SchemaType) String ¶
func (v SchemaType) String() string
type StorageSchema ¶
type StorageSchema struct {
// contains filtered or unexported fields
}
StorageSchema represents a registry schema and can be used to validate the storage.
func ParseSchema ¶
func ParseSchema(raw []byte) (*StorageSchema, error)
ParseSchema parses a JSON registry schema and returns a Schema that can be used to validate storage.
func (*StorageSchema) SchemaAt ¶
func (s *StorageSchema) SchemaAt(path []string) ([]Schema, error)
SchemaAt returns the types that may be stored at the specified path.
func (*StorageSchema) Type ¶
func (s *StorageSchema) Type() SchemaType
func (*StorageSchema) Validate ¶
func (s *StorageSchema) Validate(raw []byte) error
Validate validates the provided JSON object.
type ValidationError ¶
type ValidationError struct {
Path []interface{}
Err error
}
TODO: keep a list of expected types (to support alternatives), an actual type/value and then optional unmet constraints for the expected types. Then this could be used to have more concise errors when there are many possible types https://github.com/snapcore/snapd/pull/13502#discussion_r1463658230
func (*ValidationError) Error ¶
func (v *ValidationError) Error() string
type View ¶
type View struct {
Name string
// contains filtered or unexported fields
}
View carries access rules for a particular view in a registry.
func (*View) Get ¶
Get returns the view value identified by the request. If either the named view or the corresponding value can't be found, a NotFoundError is returned.
