Node configuration

Fields

wallet_id: Option<String>

The address to be credited when this node farms SafeCoin. A hex formatted BLS public key.

max_capacity: Option<u64>

Upper limit in bytes for allowed network storage on this node.

root_dir: Option<PathBuf>

Root directory for dbs and cached state. If not set, it defaults to “root_dir” within the sn_node project data directory, located at: Linux: $HOME/.safe/node/root_dir Windows: {FOLDERID_Profile}/.safe/node/root_dir MacOS: $HOME/.safe/node/root_dir

verbose: u8

Verbose output. -v is equivalent to logging with warn, -vv to info, -vvv to debug, -vvvv to trace. This flag overrides RUST_LOG.

completions: Option<String>

dump shell completions for: [bash, fish, zsh, powershell, elvish]

log_dir: Option<PathBuf>

Send logs to a file within the specified directory

update: bool

Attempt to self-update?

update_only: bool

Attempt to self-update without starting the node process

json_logs: bool

Outputs logs in json format for easier processing

resource_logs: bool

print node resourse usage to stdout

clear_data: bool

Delete all data from a previous node running on the same PC

first: bool

Whether the node is the first on the network.

When set, you must specify either --local-addr or --public-addr to ensure the correct connection info is stored.

local_addr: Option<SocketAddr>

Local address to be used for the node.

When unspecified, the node will listen on 0.0.0.0 with a random unused port. If you’re running a local-only network, you should set this to 127.0.0.1:0 to prevent any external traffic from reaching the node (but note that the node will also be unable to connect to non-local nodes).

public_addr: Option<SocketAddr>

External address of the node, to use when writing connection info.

If unspecified, it will be queried from a peer; if there are no peers, the local-addr will be used, if specified.

skip_auto_port_forwarding: bool

This flag can be used to skip automated port forwarding using IGD. This is used when running a network on a LAN or when a node is connected to the internet directly, without a router, e.g. Digital Ocean droplets.

hard_coded_contacts: BTreeSet<SocketAddr>

Hard Coded contacts

genesis_key: Option<String>

Genesis key of the network in hex format.

max_msg_size_allowed: Option<u32>

This is the maximum message size we’ll allow the peer to send to us. Any bigger message and we’ll error out probably shutting down the connection to the peer. If none supplied we’ll default to the documented constant.

idle_timeout_msec: Option<u64>

If we hear nothing from the peer in the given interval we declare it offline to us. If none supplied we’ll default to the documented constant.

The interval is in milliseconds. A value of 0 disables this feature.

keep_alive_interval_msec: Option<u32>

Interval to send keep-alives if we are idling so that the peer does not disconnect from us declaring us offline. If none is supplied we’ll default to the documented constant.

The interval is in milliseconds. A value of 0 disables this feature.

upnp_lease_duration: Option<u32>

Duration of a UPnP port mapping.

network_config: NetworkConfig

Implementations

impl Config

pub async fn new() -> Result<Self, Error>

Returns a new Config instance. Tries to read from the default node config file location, and overrides values with any equivalent command line args.

pub fn wallet_id(&self) -> Option<&String>

The address to be credited when this node farms SafeCoin.

pub fn is_first(&self) -> bool

Is this the first node in a section?

pub fn max_capacity(&self) -> u64

Upper limit in bytes for allowed network storage on this node.

pub fn root_dir(&self) -> Result<PathBuf>

Root directory for dbs and cached state. If not set, it defaults to DEFAULT_ROOT_DIR_NAME within the project’s data directory (see Config::root_dir for the directories on each platform).

pub fn set_root_dir<P: Into<PathBuf>>(&mut self, path: P)

Set the root directory for dbs and cached state.

pub fn set_log_dir<P: Into<PathBuf>>(&mut self, path: P)

Set the directory to write the logs.

pub fn verbose(&self) -> Level

Get the log level.

pub fn network_config(&self) -> &NetworkConfig

Network configuration options.

pub fn set_network_config(&mut self, config: NetworkConfig)

Set network configuration options.

pub fn completions(&self) -> &Option<String>

Get the completions option

pub fn log_dir(&self) -> &Option<PathBuf>

Directory where to write log file/s if specified

pub fn update(&self) -> bool

Attempt to self-update?

pub fn update_only(&self) -> bool

Attempt to self-update without starting the node process

pub async fn write_to_disk(&self) -> Result<()>

Writes the config file to disk

Trait Implementations

impl Clone for Config

fn clone(&self) -> Config

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Config

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Config

fn default() -> Config

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Config

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error> where
    __D: Deserializer<'de>, 

Deserialize this value from the given Serde deserializer.

impl Serialize for Config

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error> where
    __S: Serializer, 

Serialize this value into the given Serde serializer.

impl StructOpt for Config

fn clap<'a, 'b>() -> App<'a, 'b>

Returns clap::App corresponding to the struct.

fn from_clap(matches: &ArgMatches<'_>) -> Self

Builds the struct from clap::ArgMatches. It’s guaranteed to succeed if matches originates from an App generated by StructOpt::clap called on the same type, otherwise it must panic.

fn from_args() -> Self

Builds the struct from the command line arguments (std::env::args_os). Calls clap::Error::exit on failure, printing the error message and aborting the program.

fn from_args_safe() -> Result<Self, Error>

Builds the struct from the command line arguments (std::env::args_os). Unlike StructOpt::from_args, returns clap::Error on failure instead of aborting the program, so calling .exit is up to you.

fn from_iter<I>(iter: I) -> Self where
    I: IntoIterator,
    <I as IntoIterator>::Item: Into<OsString>,
    <I as IntoIterator>::Item: Clone, 

Gets the struct from any iterator such as a Vec of your making. Print the error message and quit the program in case of failure.

fn from_iter_safe<I>(iter: I) -> Result<Self, Error> where
    I: IntoIterator,
    <I as IntoIterator>::Item: Into<OsString>,
    <I as IntoIterator>::Item: Clone, 

Gets the struct from any iterator such as a Vec of your making.
