Implementations§

Source§

impl OnionServiceConfigBuilder

Source

pub fn nickname(&mut self, val: HsNickname) -> &mut OnionServiceConfigBuilder

Provide a value for nickname.

If no value is provided for nickname, build will fail with an error.

§nickname

The nickname used to look up this service’s keys, state, configuration, etc.

Source

pub fn enabled(&mut self, val: bool) -> &mut OnionServiceConfigBuilder

Provide a value for enabled.

If no value is provided for enabled, build will use Default::default().

§enabled

If true, this service will be started. It should be available to commands that don’t require it to start regardless.

Source

pub fn num_intro_points(&mut self, val: u8) -> &mut OnionServiceConfigBuilder

Provide a value for num_intro_points.

If no value is provided for num_intro_points, build will use Default::default().

§num_intro_points

Number of intro points; defaults to 3; max 20.

Source

pub fn rate_limit_at_intro( &mut self, val: impl PossiblyOption<TokenBucketConfig>, ) -> &mut OnionServiceConfigBuilder

Provide a value for rate_limit_at_intro.

If no value is provided for rate_limit_at_intro, build will use Default::default(). For convenience, this function accepts both TokenBucketConfig and Option<$T> .

§rate_limit_at_intro

A rate-limit on the acceptable rate of introduction requests.

We send this to the introduction point to configure how many introduction requests it sends us. If this is not set, the introduction point chooses a default based on the current consensus.

We do not enforce this limit ourselves.

This configuration is sent as a DOS_PARAMS extension, as documented in https://spec.torproject.org/rend-spec/introduction-protocol.html#EST_INTRO_DOS_EXT.

Source

pub fn max_concurrent_streams_per_circuit( &mut self, val: u32, ) -> &mut OnionServiceConfigBuilder

Provide a value for max_concurrent_streams_per_circuit.

If no value is provided for max_concurrent_streams_per_circuit, build will use Default::default().

§max_concurrent_streams_per_circuit

How many streams will we allow to be open at once for a single circuit on this service?

If a client attempts to open more than this many streams on a rendezvous circuit, the circuit will be torn down.

Equivalent to C Tor’s HiddenServiceMaxStreamsCloseCircuit option.

Source

pub fn enable_pow(&mut self, val: bool) -> &mut OnionServiceConfigBuilder

Provide a value for enable_pow.

If no value is provided for enable_pow, build will use Default::default().

§enable_pow

If true, we will require proof-of-work when we’re under heavy load.

Source

pub fn pow_rend_queue_depth( &mut self, val: usize, ) -> &mut OnionServiceConfigBuilder

Provide a value for pow_rend_queue_depth.

If no value is provided for pow_rend_queue_depth, build will use Default::default().

§pow_rend_queue_depth

The maximum number of entries allowed in the rendezvous request queue when PoW is enabled.

If you are seeing dropped requests, have a bursty traffic pattern, and have some memory to spare, you may want to increase this.

Each request will take a few KB, the default queue is expected to take 32MB at most.

Source

pub fn restricted_discovery(&mut self) -> &mut RestrictedDiscoveryConfigBuilder

Return a mutable reference to the inner builder for restricted_discovery.

§restricted_discovery

Configure restricted discovery mode.

When this is enabled, we encrypt our list of introduction point and keys so that only clients holding one of the listed keys can decrypt it.

Source

pub fn disable_pow_compilation( &mut self, val: bool, ) -> &mut OnionServiceConfigBuilder

Provide a value for disable_pow_compilation.

If no value is provided for disable_pow_compilation, build will use Default::default().

§disable_pow_compilation

Whether to use the compiled backend for proof-of-work.

Source§

impl OnionServiceConfigBuilder

Source

pub fn new() -> OnionServiceConfigBuilder

Return a new builder object.

Source

pub fn build(&self) -> Result<OnionServiceConfig, ConfigBuildError>

Try to construct a new OnionServiceConfig from the fields set in this builder.

Return an error if any required field is missing, or is set to something invalid.

Source§

impl OnionServiceConfigBuilder

Source

pub fn peek_nickname(&self) -> Option<&HsNickname>

Return the configured nickname for this service, if it has one.
