func NewProjectionFromBytes(bs []byte) (*Projection, error)
NewProjectionFromBytes creates a Projection from a stream of bytes
func NewProjectionFromFolder ¶
func NewProjectionFromFolder(specFileOrDirs ...string) (*Projection, error)
NewProjectionFromFolder creates a Projection from a folder containing spec files
func SpecLoader ¶
func SpecLoader(specFileOrDirs []string, opts SpecOpt) (*Projection, error)
SpecLoader loads spec files and parses them
func (*Projection) GetColumn ¶
