Functions ¶
func FromContext ¶
FromContext returns the tree within ctx if present, together with an indication of whether a tree was present.
func GetTree ¶
func GetTree(ctx context.Context, s storage.AdminStorage, treeID int64, opts GetOpts) (*trillian.Tree, error)
GetTree returns the specified tree, either from the ctx (if present) or read from storage. The tree will be validated according to GetOpts before returned. Tree state is also considered (for example, deleted tree will return NotFound errors).
Types ¶
type GetOpts ¶
type GetOpts struct {
// TreeTypes is a set of allowed tree types. If empty, any type is allowed.
TreeTypes map[trillian.TreeType]bool
// Operation indicates what operation is being performed.
Operation OpType
}
GetOpts contains validation options for GetTree.
type OpType ¶ added in v1.0.7
type OpType int
OpType indicates how a tree is to be used and participates in permissions decisions.
const ( // Unknown is an access type that will always get rejected. Unknown OpType = iota // Admin access is for general administration purposes. Admin // Query implies access to serve query, typically readonly. Query // QueueLog is log specific - adding entries to the queue. QueueLog // SequenceLog is log specific - integrating entries into the tree. SequenceLog // UpdateMap is map specific - set / update leaves. UpdateMap )
