Types

type CueInput

type CueInput struct {
	InputBase `yaml:",inline"`

	// Entrypoint refers to a directory containing CUE files.
	Entrypoint string `yaml:"entrypoint"`

	// Value represents the CUE value to use as an input. If specified, it
	// supersedes the Entrypoint option.
	Value *cue.Value `yaml:"-"`

	// ForcedEnvelope decorates the parsed cue Value with an envelope whose
	// name is given. This is useful for dataqueries for example, where the
	// schema doesn't define any suitable top-level object.
	ForcedEnvelope string `yaml:"forced_envelope"`

	// Package name to use for the input schema. If empty, it will be guessed
	// from the entrypoint.
	Package string `yaml:"package"`

	// CueImports allows importing additional libraries.
	// Format: [path]:[import]. Example: '../grafana/common-library:github.com/grafana/grafana/packages/grafana-schema/src/common
	CueImports []string `yaml:"cue_imports"`

	NameFunc simplecue.NameFunc `yaml:"-"`
}

type InputBase

type InputBase struct {
	// AllowedObjects is a list of object names that will be allowed when
	// parsing the input schema.
