Functions

func DedupAndCalculatePinSize 

func DedupAndCalculatePinSize(hash string, im Manager) (int64, []string, error)

DedupAndCalculatePinSize is used to remove duplicate refers to objects for a more accurate pin size cost it returns the size of all refs, as well as all unique references

func MnemonicToKey 

func MnemonicToKey(phrase string) (ci.PrivKey, error)

MnemonicToKey takes an exported mnemonic phrase, and converts it to a private key

Types

type IpfsManager 

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

IpfsManager is our helper wrapper for IPFS

func NewManager added in v0.2.0 

func NewManager(ipfsURL, token string, timeout time.Duration) (*IpfsManager, error)

NewManager is used to instantiate IpfsManager with a connection to an ipfs api. if token is provided, we use it to establish an authentication, direct connection to an ipfs node api, which involves skipping multiaddr parsing. This is useful in situations such as interacting with Nexus' delegator to talk with private ipfs networks which use non-standard connection methods.

func (*IpfsManager) Add 

func (im *IpfsManager) Add(r io.Reader, options ...ipfsapi.AddOpts) (string, error)

Add is a wrapper used to add a file to IPFS

func (*IpfsManager) AddDir 

func (im *IpfsManager) AddDir(dir string) (string, error)

AddDir is used to add a directory to ipfs

func (*IpfsManager) AppendData 

func (im *IpfsManager) AppendData(root string, data interface{}) (string, error)

AppendData is used to modify the raw data within an object, to a max of 1MB Anything larger than 1MB will not be respected by the rest of the network

func (*IpfsManager) Cat 

func (im *IpfsManager) Cat(cid string) ([]byte, error)

Cat is used to get cat an ipfs object

func (*IpfsManager) CheckPin 

func (im *IpfsManager) CheckPin(hash string) (bool, error)

CheckPin checks whether or not a pin is present

func (*IpfsManager) CustomRequest 

func (im *IpfsManager) CustomRequest(ctx context.Context, url, commad string,
	opts map[string]string, args ...string) (*ipfsapi.Response, error)

CustomRequest is used to make a custom request

func (*IpfsManager) DagGet 

func (im *IpfsManager) DagGet(cid string, out interface{}) error

DagGet is used to get an ipld object

func (*IpfsManager) DagPut 

func (im *IpfsManager) DagPut(data interface{}, encoding, kind string) (string, error)

DagPut is used to store data as an ipld object

func (*IpfsManager) NewObject 

func (im *IpfsManager) NewObject(template string) (string, error)

NewObject is used to create a generic object from a template type

func (*IpfsManager) NodeAddress 

func (im *IpfsManager) NodeAddress() string

NodeAddress returns the node the manager is connected to 

func (im *IpfsManager) PatchLink(root, path, childHash string, create bool) (string, error)

PatchLink is used to link two objects together path really means the name of the link create is used to specify whether intermediary nodes should be generated

func (*IpfsManager) Pin 

func (im *IpfsManager) Pin(hash string) error

Pin is a wrapper method to pin a hash. pinning prevents GC and persistently stores on disk

func (*IpfsManager) PinUpdate 

func (im *IpfsManager) PinUpdate(from, to string) (string, error)

PinUpdate is used to update one pin to another, while making sure all objects in the new pin are local, followed by removing the old pin.

This is an optimized version of pinning the new content, and then removing the old content.

returns the new pin path

func (*IpfsManager) PubSubPublish 

func (im *IpfsManager) PubSubPublish(topic string, data string) error

PubSubPublish is used to publish a a message to the given topic

func (*IpfsManager) Publish 

func (im *IpfsManager) Publish(contentHash, keyName string, lifetime, ttl time.Duration, resolve bool) (*ipfsapi.PublishResponse, error)

Publish is used for fine grained control over IPNS record publishing

func (*IpfsManager) Refs 

func (im *IpfsManager) Refs(hash string, recursive, unique bool) ([]string, error)

Refs is used to retrieve references of a hash

func (*IpfsManager) Resolve 

func (im *IpfsManager) Resolve(hash string) (string, error)

Resolve is used to resolve an IPNS hash

func (*IpfsManager) SetData 

func (im *IpfsManager) SetData(root string, data interface{}) (string, error)

SetData is used to set the data field of an ipfs object

func (*IpfsManager) Stat 

func (im *IpfsManager) Stat(hash string) (*ipfsapi.ObjectStats, error)

Stat is used to retrieve the stats about an object

func (*IpfsManager) SwarmConnect 

func (im *IpfsManager) SwarmConnect(ctx context.Context, addrs ...string) error

SwarmConnect is use to open a connection a one or more ipfs nodes

type KeystoreManager 

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

KeystoreManager is howe we manipulat keys

func NewKeystoreManager added in v0.2.0 

func NewKeystoreManager(store *krab.Krab) (*KeystoreManager, error)

NewKeystoreManager instantiates a new keystore manager. Takes an optional filepath for the store.

func (*KeystoreManager) CheckIfKeyExists 

func (km *KeystoreManager) CheckIfKeyExists(keyName string) (bool, error)

CheckIfKeyExists is used to check if a key exists

func (*KeystoreManager) ExportKeyAsMnemonic 

func (km *KeystoreManager) ExportKeyAsMnemonic(keyName string) (string, error)

ExportKeyAsMnemonic is used to take an IPFS key, and return a human-readable friendly version. The idea is to allow users to easily export the keys they create, allowing them to take control of their records (ipns, tns, etc..)
