Types

type Cache

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

func New

func New(options func(*source.Options)) *Cache

func (*Cache) FileSet

func (c *Cache) FileSet() *token.FileSet

func (*Cache) GetFile

func (c *Cache) GetFile(ctx context.Context, uri span.URI) (source.FileHandle, error)

func (*Cache) ID

func (c *Cache) ID() string

func (*Cache) MemStats

func (c *Cache) MemStats() map[reflect.Type]int

func (*Cache) NewSession

func (c *Cache) NewSession(ctx context.Context) *Session

func (*Cache) PackageStats

func (c *Cache) PackageStats(withNames bool) template.HTML

type KnownMetadata

type KnownMetadata struct {
	*Metadata

	// Valid is true if the given metadata is Valid.
	// Invalid metadata can still be used if a metadata reload fails.
	Valid bool

	// ShouldLoad is true if the given metadata should be reloaded.
	ShouldLoad bool
}

KnownMetadata is a wrapper around metadata that tracks its validity.

type Metadata

type Metadata struct {
	ID              PackageID
	PkgPath         PackagePath
	Name            PackageName
	GoFiles         []span.URI
	CompiledGoFiles []span.URI
	ForTest         PackagePath
	TypesSizes      types.Sizes
	Errors          []packages.Error
	Deps            []PackageID
	MissingDeps     map[PackagePath]struct{}
	Module          *packages.Module

	// Config is the *packages.Config associated with the loaded package.
	Config *packages.Config

	// IsIntermediateTestVariant reports whether the given package is an
	// intermediate test variant, e.g.
	// "golang.org/x/tools/internal/lsp/cache [golang.org/x/tools/internal/lsp/source.test]".
	IsIntermediateTestVariant bool
	// contains filtered or unexported fields
}

Metadata holds package Metadata extracted from a call to packages.Load.

func (*Metadata) PackageName

func (m *Metadata) PackageName() string

Name implements the source.Metadata interface.

func (*Metadata) PackagePath

func (m *Metadata) PackagePath() string

PkgPath implements the source.Metadata interface.

type PackageID

type PackageID string

Declare explicit types for package paths, names, and IDs to ensure that we never use an ID where a path belongs, and vice versa. If we confused these, it would result in confusing errors because package IDs often look like package paths.

type PackageName

type PackageName string

Declare explicit types for package paths, names, and IDs to ensure that we never use an ID where a path belongs, and vice versa. If we confused these, it would result in confusing errors because package IDs often look like package paths.

type PackagePath

type PackagePath string

Declare explicit types for package paths, names, and IDs to ensure that we never use an ID where a path belongs, and vice versa. If we confused these, it would result in confusing errors because package IDs often look like package paths.
