type BookmarksJar

type BookmarksJar interface {
	// Save saves a bookmark with the given name.
	Save(name, url string) error

	// Read returns the URL for the bookmark with the given name.
	Read(name string) (string, error)

	// Remove deletes the bookmark with the given name.
	Remove(name string) bool

	// Has returns a boolean value indicating whether a bookmark exists with the given name.
	Has(name string) bool

	// All returns all of the bookmarks as a BookmarksMap.
	All() BookmarksMap
}

type FileBookmarks

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

FileBookmarks is an implementation of BookmarksJar that saves to a file.

func NewFileBookmarks

func NewFileBookmarks(file string) (*FileBookmarks, error)

NewFileBookmarks creates and returns a new *FileBookmarks type.

func (*FileBookmarks) All

func (b *FileBookmarks) All() BookmarksMap

All returns all of the bookmarks as a BookmarksMap.

func (*FileBookmarks) Has

func (b *FileBookmarks) Has(name string) bool

Has returns a boolean value indicating whether a bookmark exists with the given name.

func (*FileBookmarks) Read

func (b *FileBookmarks) Read(name string) (string, error)

	Clear()
	SetMax(max int)
	Len() int
	Push(p *State) int
	Pop() *State
	Top() *State
}

History is a type that records browser state.

type MemoryBookmarks
