Functions ¶

func FileSystem ¶

func FileSystem() http.FileSystem

FileSystem returns an in-memory filesystem including the schema files. The schema files are located at the root directory.

func WrapSyntaxError ¶

func WrapSyntaxError(r io.Reader, err error) error

WrapSyntaxError checks whether the given error is a *json.SyntaxError and converts it into a *schema.SyntaxError containing line/col information using the given reader. If the given error is not a *json.SyntaxError it is returned unchanged.

Types ¶

type SyntaxError ¶

type SyntaxError struct {
	Line, Col int
	Offset    int64
	// contains filtered or unexported fields
}

A SyntaxError is a description of a JSON syntax error including line, column and offset in the JSON file.

func (*SyntaxError) Error ¶

func (e *SyntaxError) Error() string

type ValidationError ¶

type ValidationError struct {
	Errs []error
}

ValidationError contains all the errors that happened during validation.

func (ValidationError) Error ¶

func (e ValidationError) Error() string

type Validator ¶

type Validator string

Validator wraps a media type string identifier and implements validation against a JSON schema.

func (Validator) Validate ¶

func (v Validator) Validate(src io.Reader) error

Validate validates the given reader against the schema of the wrapped media type.
