Constants

const (
	// TargetRego is the default target. The source rego is copied (potentially
	// rewritten for optimization purpsoes) into the bundle. The target supports
	// base documents.
	TargetRego = "rego"

	// TargetWasm is an alternative target that compiles the policy into a wasm
	// module instead of Rego. The target supports base documents.
	TargetWasm = "wasm"

	// TargetPlan is an altertive target that compiles the policy into an
	// imperative query plan that can be further transpiled or interpreted.
	TargetPlan = "plan"
)

Variables

var Targets = []string{
	TargetRego,
	TargetWasm,
	TargetPlan,
}

Targets contains the list of targets supported by the compiler.

Types

type Compiler

type Compiler struct {
	// contains filtered or unexported fields
}

Compiler implements bundle compilation and linking.

func New

func New() *Compiler

New returns a new compiler instance that can be invoked.

func (*Compiler) Build

func (c *Compiler) Build(ctx context.Context) error

Build compiles and links the input files and outputs a bundle to the writer.

func (*Compiler) Bundle

func (c *Compiler) Bundle() *bundle.Bundle

Bundle returns the compiled bundle. This function can be called to retrieve the output of the compiler (as an alternative to having the bundle written to a stream.)

func (*Compiler) WithAsBundle

func (c *Compiler) WithAsBundle(enabled bool) *Compiler

WithAsBundle sets file loading mode on the compiler.

func (*Compiler) WithBundle

func (c *Compiler) WithBundle(b *bundle.Bundle) *Compiler

WithBundle sets the input bundle to compile. This should be used as an alternative to reading from paths. This function overrides any file loading options.

func (*Compiler) WithBundleSigningConfig

func (c *Compiler) WithBundleSigningConfig(config *bundle.SigningConfig) *Compiler

WithBundleSigningConfig sets the key configuration to use to generate a signed bundle

func (*Compiler) WithBundleVerificationConfig

func (c *Compiler) WithBundleVerificationConfig(config *bundle.VerificationConfig) *Compiler

WithBundleVerificationConfig sets the key configuration to use to verify a signed bundle

func (*Compiler) WithBundleVerificationKeyID

func (c *Compiler) WithBundleVerificationKeyID(keyID string) *Compiler

WithBundleVerificationKeyID sets the key to use to verify a signed bundle. If provided, the "keyid" claim in the bundle signature, will be set to this value

func (*Compiler) WithCapabilities

func (c *Compiler) WithCapabilities(capabilities *ast.Capabilities) *Compiler

WithCapabilities sets the capabilities to use while checking policies.

func (*Compiler) WithDebug

func (c *Compiler) WithDebug(sink io.Writer) *Compiler

WithDebug sets the output stream to write debug info to.

func (*Compiler) WithEntrypoints

func (c *Compiler) WithEntrypoints(e ...string) *Compiler

WithEntrypoints sets the policy entrypoints on the compiler. Entrypoints tell the compiler what rules to expect and where optimizations can be targeted. The wasm target requires at least one entrypoint as does optimization.

func (*Compiler) WithFilter

func (c *Compiler) WithFilter(filter loader.Filter) *Compiler

WithFilter sets the loader filter to use when reading non-bundle input files.

func (*Compiler) WithMetadata

func (c *Compiler) WithMetadata(metadata *map[string]interface{}) *Compiler

WithMetadata sets the additional data to be included in .manifest

func (*Compiler) WithOptimizationLevel

func (c *Compiler) WithOptimizationLevel(n int) *Compiler

WithOptimizationLevel sets the optimization level on the compiler. By default optimizations are disabled. Higher levels apply more aggressive optimizations but can take longer.

func (*Compiler) WithOutput

func (c *Compiler) WithOutput(w io.Writer) *Compiler

WithOutput sets the output stream to write the bundle to.

func (*Compiler) WithPaths

func (c *Compiler) WithPaths(p ...string) *Compiler

WithPaths adds input filepaths to read policy and data from.

func (*Compiler) WithRevision

func (c *Compiler) WithRevision(r string) *Compiler

WithRevision sets the revision to include in the output bundle manifest.

func (*Compiler) WithTarget

func (c *Compiler) WithTarget(t string) *Compiler

WithTarget sets the output target type to use.
