Implementations

impl Client

pub async fn read_bytes(&self, address: BytesAddress) -> Result<Bytes>

Reads Bytes from the network, whose contents are contained within on or more chunks.

pub async fn read_from(
    &self,
    address: BytesAddress,
    position: usize,
    length: usize
) -> Result<Bytes> where
    Self: Sized, 

Read bytes from the network. The contents are spread across multiple chunks in the network. This function invokes the self-encryptor and returns the data that was initially stored.

Takes position and length arguments which specify the start position and the length of bytes to be read. Passing 0 to position reads the data from the beginning, and the length is just an upper limit.

Examples

TODO: update once data types are crdt compliant

pub fn chunk_bytes(
    &self,
    bytes: Bytes,
    scope: Scope
) -> Result<(BytesAddress, Vec<Chunk>)>

Tries to chunk the bytes, returning an address and chunks, without storing anything to network.

pub async fn upload(&self, bytes: Bytes, scope: Scope) -> Result<BytesAddress>

Directly writes Bytes to the network in the form of immutable chunks, without any batching.

pub async fn upload_and_verify(
    &self,
    bytes: Bytes,
    scope: Scope
) -> Result<BytesAddress>

Directly writes a [Blob] to the network in the form of immutable self encrypted chunks, without any batching. It also attempts to verify the Blob was uploaded to the network before returning.

pub fn calculate_address(bytes: Bytes, scope: Scope) -> Result<BytesAddress>

Calculates a Blob’s/Spot’s address from self encrypted chunks, without storing them onto the network.

impl Client

pub async fn send_signed_command(
    &self,
    dst_address: XorName,
    client_pk: PublicKey,
    serialised_cmd: Bytes,
    signature: Signature,
    targets: usize
) -> Result<(), Error>

Send a signed DataCmd to the network. This is to be part of a public API, for the user to provide the serialised and already signed command.

impl Client

pub async fn send_query(&self, query: DataQuery) -> Result<QueryResult, Error>

Send a Query to the network and await a response. Queries are automatically retried using exponential backoff if the timeout is hit.

pub async fn send_query_without_retry(
    &self,
    query: DataQuery
) -> Result<QueryResult, Error>

Send a Query to the network and await a response. Queries are not retried if the timeout is hit.

pub async fn send_signed_query(
    &self,
    query: DataQuery,
    client_pk: PublicKey,
    serialised_query: Bytes,
    signature: Signature
) -> Result<QueryResult, Error>

Send a Query to the network and await a response. This is part of a public API, for the user to provide the serialised and already signed query.

impl Client

pub async fn publish_register_ops(
    &self,
    wal: RegisterWriteAheadLog
) -> Result<(), Error>

Publish all register mutation operations in a WAL to the network Incrementing the WAL index as successful writes are sent out. Stops at the first error. Starts publishing from the index when called again with the same WAL.

pub async fn store_private_register(
    &self,
    name: XorName,
    tag: u64,
    owner: PublicKey,
    permissions: BTreeMap<PublicKey, PrivatePermissions>
) -> Result<(Address, RegisterWriteAheadLog), Error>

Create a Private Register onto the Network

Creates a private Register on the network which can then be written to. Private data can be removed from the network at a later date.

Returns a write ahead log (WAL) of register operations, note that the changes are not uploaded to the network until the WAL is published with publish_register_ops

A tag must be supplied. A xorname must be supplied, this can be random or deterministic as per your apps needs.

pub async fn store_public_register(
    &self,
    name: XorName,
    tag: u64,
    owner: PublicKey,
    permissions: BTreeMap<User, PublicPermissions>
) -> Result<(Address, RegisterWriteAheadLog), Error>

Create a Public Register onto the Network

Creates a public Register on the network which can then be written to. Public data can not be removed from the network at a later date.

Returns a write ahead log (WAL) of register operations, note that the changes are not uploaded to the network until the WAL is published with publish_register_ops

A tag must be supplied. A xorname must be supplied, this can be random or deterministic as per your apps needs.

pub async fn delete_register(
    &self,
    address: Address
) -> Result<RegisterWriteAheadLog, Error>

Delete Register

Returns a write ahead log (WAL) of register operations, note that the changes are not uploaded to the network until the WAL is published with publish_register_ops

You’re only able to delete a PrivateRegister. Public data can not be removed from the network.

pub async fn write_to_register(
    &self,
    address: Address,
    entry: Entry,
    children: BTreeSet<EntryHash>
) -> Result<(EntryHash, RegisterWriteAheadLog), Error>

Write to Register

Returns a write ahead log (WAL) of register operations, note that the changes are not uploaded to the network until the WAL is published with publish_register_ops

Public or private isn’t important for writing, though the data you write will be Public or Private according to the type of the targeted Register.

pub async fn get_register(&self, address: Address) -> Result<Register, Error>

Get a Register from the Network

pub async fn read_register(
    &self,
    address: Address
) -> Result<BTreeSet<(EntryHash, Entry)>, Error>

Get the last data entry from a Register data.

pub async fn get_register_entry(
    &self,
    address: Address,
    hash: EntryHash
) -> Result<Entry, Error>

Get an entry from a Register on the Network by its hash

pub async fn get_register_owner(
    &self,
    address: Address
) -> Result<PublicKey, Error>

Get the owner of a Register.

pub async fn get_register_permissions_for_user(
    &self,
    address: Address,
    user: PublicKey
) -> Result<Permissions, Error>

Get the set of Permissions in a Register for a specific user.

pub async fn get_register_policy(
    &self,
    address: Address
) -> Result<Policy, Error>

Get the Policy of a Register.

impl Client

Easily manage connections to/from The Safe Network with the client and its APIs. Use a random client for read-only or one-time operations. Supply an existing, SecretKey which holds a SafeCoin balance to be able to perform write operations.

pub async fn new(
    config: ClientConfig,
    bootstrap_nodes: BTreeSet<SocketAddr>,
    optional_keypair: Option<Keypair>
) -> Result<Self, Error>

Create a Safe Network client instance. Either for an existing SecretKey (in which case) the client will attempt to retrieve the history of the key’s balance in order to be ready for any token operations. Or if no SecreteKey is passed, a random keypair will be used, which provides a client that can only perform Read operations (at least until the client’s SecretKey receives some token).

Examples

TODO: update once data types are crdt compliant

pub fn keypair(&self) -> Keypair

Return the client’s keypair.

Useful for retrieving the PublicKey or KeyPair in the event you need to sign something

Examples

TODO: update once data types are crdt compliant

pub fn public_key(&self) -> PublicKey

Return the client’s PublicKey.
